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.

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.

The correct answer is 4 hours

What is function?

A function is an expression that defines the relation between an input to an output.

What is simplification?

It is the process that replaces a mathematical expression by an equivalent one, that is simpler and shorter.

How to solve the problem?

The problem can be solved by following steps
The equation given is f(h) = 50h +75
f(h) given is $275
We need to calculate the h numbers of hours worked.

So , In equation

f(h)=50h+75

Substitute the value of f(h) in equation

Therefore , 275 = 50(h)+75

Simplifying the equation

275-75 = 50h

Therefore, 200=50h

∴ h = 200/50

∴ h= 4 hours

Hence the number of hours worked is 4 hours
