Question

1. levi signed up for a streaming music service that costs $7 per month. the service allows levi to listen to unlimited music, but if he wants to download songs for offline listening, the service charges $1.50 per song. how much total money would levi have to pay in a month in which he downloaded 15 songs? how much would he have to pay if he downloaded s songs?

Explanation:

Step1: Calculate cost for 15 songs

The cost for downloading 15 songs is \(15\times1.50 = 22.5\) dollars. The monthly service cost is $7. So the total cost is \(7+22.5\).

Step2: Calculate total cost

\(7 + 22.5=29.5\) dollars.

For \(s\) songs:

Step1: Set up the formula

The cost for downloading \(s\) songs is \(1.5s\) dollars. The monthly service cost is $7. So the total cost \(C\) is \(C = 7+1.5s\).

Answer:

When downloading 15 songs, Levi has to pay \(\$29.5\). When downloading \(s\) songs, he has to pay \(\$(7 + 1.5s)\).
