Question

A computer company uses the function f(h) = 50h + 75 to calculate the total repair bill, f(h), for h number of hours worked. Find h if f(h) = $275.

Answer 1

Well first put the equation as a whole because you have f(h),275=50h+75. Now we have to get h by itself to get its value.
1. Move 75 over to the left by subtracting it for 200=50h
2. Now divide by 50 to get h alone. 4=h
You now know that the value of h is 4.
