Complete Question:

A music website offering unlimited listening to subscribers charges a one time fee of $12 to join with an additional $6 per month usage fee.

Given that Anna wants to spend less than $60 for the subscription and only full month subscriptions are offered, what is the maximum number of months that Anna can subscribe?

Answer:

7 months

Explanation:

Given

`Initial =12`

`Rate = 6`

Let the total charges for x months be y.

The equation is generated as:

`y = Initial + Rate* x`

This gives:

`y = 12 + 6* x`

`y = 12 + 6x`

If Anna wants to spend less than $60.

Then the equation becomes:

`y < 60`

Substitute:
`y = 12 + 6x`

`12 +6x < 60`

Collect like terms

`6x < 60 -12`

`6x < 48`

Solve for x

`x < 48/6`

`x < 8`

This implies that she will spend for a maximum of 7 months (because 7 < 8)
