Question

a computer company uses the function f(h) =50h+75 to calculate the total repair bill, f(h) for h numbers of hours worked find h if f(h) =275

Answer 1

The answer is four because it's 275-75 divided by fifty

Answer 2

If f(h)=275 then 275=50h+75
Then combine like terms so
275=50h+75
-75 -75
200=50h
Then get h by itself
200=50h
/50 /50
4=h
