The function f(x) = 10x + 15 models the amount of money, in dollars,

that Jack earns shoveling snow

for x hours. How many dollars will

Jack make in 4 hours of shoveling

snow?

$55

Step-by-step explanation:

X represents the amount of hours that Jack shovels for and it says that he shoveled for four hours. All you have to do it plug 4 into the equation. It will be 10(4)+15. After you simplify it you will see that he gets 55 dollars for four hours of work.
