Tyler needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 5 hours and charged him $112 for parts. The total was $237. What was the cost of labor, per hour?

$25 dollars per hour

Step-by-step explanation:

I subtracted the parts (Doesn't count), and I took the remaining balance and divided it by 5 hours to get the amount per hour.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
