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

h = 4

Explanation:

create the equation:

275 = 50h + 75

subtract 75 from both sides:

200 = 50h

divide both sides by 50:

h = 4

Answer 2

h=4 because 50x4=200+75 is 275
