Answer 1

23 boxes of toys are being stored.

Explanation:

There is a fixed cost of $1200 a month for rent and a variable cost of $5 per box of toys that are stored

This means that for x boxes of toys stored, the total cost is of:

`C(x) = 1200 + 5x`

If the total cost for this month was $1315, how many boxes of toys are being stored?

This is
`x` for which
`C(x) = 1315`. So

`C(x) = 1200 + 5x`

`1315 = 1200 + 5x`

`5x = 115`

`x = (115)/(5)`

`x = 23`

23 boxes of toys are being stored.
