Question

The relationship between the base and rate a plumber charges and his hourly fee is modeled by the linear function f (x) = 25x + 100 where x is the number of hours he works. What is the total bill if the plumber works for 6 hours ?

Answer 1

F(6)=25(6)+100
f(6)=150+100
f(6)=250
Final answer: $250
