Question

Angel signed up for a streaming music service that costs $11 per month. The

service allows Angel 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 Angel have to pay in a month in which he downloaded 25
songs? How much would he have to pay if he downloaded s songs?
Cost for 25 songs:
Cost for s songs:

Answer 1

Cost for 25 songs: $23.50

Cost for s songs: .50(s) + 11

Explanation:

To solve this problem, we can make an equation in slope-intercept form:

y = mx + b

y represents the total amount of $.

m represents the cost of each song downloaded, or $.50

x represents the number of songs, or 's'

b represents the $11, or the constant.

We have the equation:

y = .50(x) + 11

If Angel downloaded 25 songs, we have the equation:

y = .50(25) + 11

We get y = $23.50

Hope this helps!
