Question

Alexander signed up for a streaming music service that costs $9 per month. The service allows Alexander to listen to unlimited music, but if he wants to download songs for offline listening, the service charges $0.50 per song. How much total money would Alexander have to pay in a month in which he downloaded 15 songs? How much would he have to pay if he downloaded s songs?

Answer 1

Or y=0.5x+9
