Question

Yo please help! Suppose the function f(x)=7x+2 represents the cost to pay a babysitter for x hours. Gina has $10.00. How much more money does Gina need if she wants to pay for 5 hours of babysitting?

Enter your answer in the box below.

Answer 1

$ 27.00

Explanation:

The given function is

`f(x)=7x+2`

If Gina wants to pay for 5 hours of babysitting, then she must have;

`f(5)=7(5)+2`

`f(5)=35+2`

`f(5)=37` dollars.

If Gina has $10.00, then she needs

37-10=27 more dollars.
