Part 1

A band expects to put 16 songs on their next CD. The band writes and records 75% more songs than they expect to put on the CD. During the editing process, 75% of the songs are removed. How many songs will there be in the end?

Understanding the Problem

To solve this problem, we need to follow a step-by-step approach. First, we need to calculate the number of songs the band writes and records, which is 75% more than the expected number of songs on the CD. Then, we need to calculate the number of songs remaining after 75% of the songs are removed during the editing process.

Calculating the Number of Songs Written and Recorded

Let's assume the number of songs the band expects to put on the CD is x. Since the band writes and records 75% more songs than they expect to put on the CD, the number of songs written and recorded is x + 75% of x.

Mathematically, this can be represented as:

x + (75/100) × x = x + 0.75x = 1.75x

Since the band expects to put 16 songs on the CD, we can substitute x = 16 into the equation:

1.75x = 1.75(16) = 28

So, the band writes and records 28 songs.

Calculating the Number of Songs Remaining After Editing

During the editing process, 75% of the songs are removed. To calculate the number of songs remaining, we need to find 25% of the total number of songs written and recorded, which is 28.

Mathematically, this can be represented as:

25% of 28 = (25/100) × 28 = 0.25 × 28 = 7

So, 7 songs will remain after the editing process.

Conclusion

In conclusion, the band writes and records 28 songs, and after the editing process, 7 songs will remain on the CD.
