7. A DJ is shopping for cloud storage for his music collection. He finds an online data storage cloud with the following monthly charges per GB (or fraction
thereof): $0.29/GB for 0 < x ≤ 25 GB, $0.26/GB for 25 < x ≤ 50 GB, $0.23/GB for
50 < x ≤ 75 GB, and $0.20/GB for x > 75 GB. What is the difference in price for
storing just the 75 GB and for storing 75 GB plus a new music collection that is
1 GB or less?
