Suppose You Are Able to Download 1 Free Song to Your Tablet Daily and Each Additional Download Costs $0.59

Understanding the Problem

In this problem, we are given a scenario where a person can download 1 free song to their tablet daily, and each additional download costs $0.59. The person's monthly bill is $15.34, and they have downloaded 28 free songs. We need to find out how many additional songs they have downloaded.

Setting Up the Equation

Let's assume that the person has downloaded x additional songs beyond the 28 free songs. Since each additional download costs $0.59, the total cost of these additional downloads is 0.59x.

The person's monthly bill is $15.34, which includes the cost of the 28 free songs and the additional downloads. Since the 28 free songs are free, their cost is $0. The total cost of the additional downloads is 0.59x.

We can set up an equation to represent this situation:

0.59x + 0 = 15.34 - 0

Simplifying the Equation

Since the cost of the 28 free songs is $0, we can simplify the equation by removing the 0 on the left-hand side:

0.59x = 15.34

Solving for x

To solve for x, we need to isolate x on one side of the equation. We can do this by dividing both sides of the equation by 0.59:

x = 15.34 / 0.59

x = 25.93

Rounding x to the Nearest Whole Number

Since we can't download a fraction of a song, we need to round x to the nearest whole number. In this case, we round 25.93 to 26.

Conclusion

Therefore, the person has downloaded 26 additional songs beyond the 28 free songs.

Discussion

This problem involves a simple algebraic equation, where we need to isolate the variable x to find the solution. The equation is:

0.59x = 15.34

To solve for x, we divide both sides of the equation by 0.59, which gives us:

x = 15.34 / 0.59

x = 25.93

Rounding x to the nearest whole number, we get x = 26.

Additional Discussion

This problem can be solved using other methods, such as:

Using a calculator to divide 15.34 by 0.59
Converting the decimal to a fraction and then dividing
Using a spreadsheet to solve the equation

However, the algebraic method is the most straightforward and efficient way to solve this problem.

Real-World Applications

This problem has real-world applications in various fields, such as:

Music streaming services, where users can download songs for a fee
Online shopping, where users can purchase digital products for a fee
Budgeting and finance, where users need to track their expenses and income

Conclusion

In conclusion, this problem involves a simple algebraic equation, where we need to isolate the variable x to find the solution. The equation is:

0.59x = 15.34

To solve for x, we divide both sides of the equation by 0.59, which gives us:

x = 15.34 / 0.59

x = 25.93

Rounding x to the nearest whole number, we get x = 26.

This problem has real-world applications in various fields, and the algebraic method is the most straightforward and efficient way to solve it.

Q&A: Additional Questions and Answers

Q: What if the person's monthly bill is $20.00 instead of $15.34? How many additional songs would they have downloaded?

A: To find the number of additional songs, we need to set up a new equation. Let's assume that the person has downloaded x additional songs beyond the 28 free songs. Since each additional download costs $0.59, the total cost of these additional downloads is 0.59x.

The person's monthly bill is $20.00, which includes the cost of the 28 free songs and the additional downloads. Since the 28 free songs are free, their cost is $0. The total cost of the additional downloads is 0.59x.

We can set up an equation to represent this situation:

0.59x = 20.00 - 0

Simplifying the equation, we get:

0.59x = 20.00

To solve for x, we divide both sides of the equation by 0.59:

x = 20.00 / 0.59

x = 33.90

Rounding x to the nearest whole number, we get x = 34.

Therefore, the person would have downloaded 34 additional songs beyond the 28 free songs.

Q: What if the cost of each additional download is $0.49 instead of $0.59? How many additional songs would the person have downloaded?

A: To find the number of additional songs, we need to set up a new equation. Let's assume that the person has downloaded x additional songs beyond the 28 free songs. Since each additional download costs $0.49, the total cost of these additional downloads is 0.49x.

We can set up an equation to represent this situation:

0.49x = 15.34 - 0

Simplifying the equation, we get:

0.49x = 15.34

To solve for x, we divide both sides of the equation by 0.49:

x = 15.34 / 0.49

x = 31.33

Rounding x to the nearest whole number, we get x = 31.

Therefore, the person would have downloaded 31 additional songs beyond the 28 free songs.

Q: What if the person has downloaded 30 free songs instead of 28? How many additional songs would they have downloaded?

A: To find the number of additional songs, we need to set up a new equation. Let's assume that the person has downloaded x additional songs beyond the 30 free songs. Since each additional download costs $0.59, the total cost of these additional downloads is 0.59x.

The person's monthly bill is $15.34, which includes the cost of the 30 free songs and the additional downloads. Since the 30 free songs are free, their cost is $0. The total cost of the additional downloads is 0.59x.

We can set up an equation to represent this situation:

0.59x = 15.34 - 0

Simplifying the equation, we get:

0.59x = 15.34

To solve for x, we divide both sides of the equation by 0.59:

x = 15.34 / 0.59

x = 25.93

Rounding x to the nearest whole number, we get x = 26.

Therefore, the person would have downloaded 26 additional songs beyond the 30 free songs.

Q: What if the cost of each additional download is $0.69 instead of $0.59? How many additional songs would the person have downloaded?

A: To find the number of additional songs, we need to set up a new equation. Let's assume that the person has downloaded x additional songs beyond the 28 free songs. Since each additional download costs $0.69, the total cost of these additional downloads is 0.69x.

We can set up an equation to represent this situation:

0.69x = 15.34 - 0

Simplifying the equation, we get:

0.69x = 15.34

To solve for x, we divide both sides of the equation by 0.69:

x = 15.34 / 0.69

x = 22.25

Rounding x to the nearest whole number, we get x = 22.

Therefore, the person would have downloaded 22 additional songs beyond the 28 free songs.

Conclusion

In conclusion, we have answered several questions related to the problem of downloading songs for a fee. We have used algebraic equations to find the number of additional songs that the person would have downloaded in different scenarios. The equations were:

0.59x = 20.00 - 0
0.49x = 15.34 - 0
0.59x = 15.34 - 0
0.69x = 15.34 - 0

We have solved these equations to find the number of additional songs that the person would have downloaded in each scenario. The answers were:

34 additional songs
31 additional songs
26 additional songs
22 additional songs

These questions and answers demonstrate the importance of algebraic equations in solving real-world problems.
