Question

A group of artists is selling small prints to raise money for charity. They sell p prints, and make a profit of f(p) on the sales. If f(p) =17p-340 which statement is true

Answer 1

If they sells 15 prints they will lose $85.

Explanation:

Consider the provided function.

`f(p) =17p-340`

First find If the group sells 15 prints, how much they will lose.

Substitute p=15 in above equation.

`f(p) =17(15)-340`

`f(p) =255-340`

`f(p) =-85`

If they sells 15 prints they will lose $85.

Find if the group sells 12 prints, how much they will lose.

Substitute p=12 in above equation.

`f(p) =17(12)-340`

`f(p) =204-340`

`f(p) =-136`

If they sells 12 prints they will lose $136.

Find if the group sells 35 prints, how much they will make.

Substitute p=35 in above equation.

`f(p) =17(35)-340`

`f(p) =595-340`

`f(p) =255`

If they sells 35 prints they will gain $255.

If the group sells 28 prints, how much they will make.

Substitute p=28 in above equation.

`f(p) =17(28)-340`

`f(p) =476-340`

`f(p) =136`

If they sells 28 prints they will gain $136.

Hence, the true statement is If they sells 15 prints they will lose $85.
