The expression $60h + $40 is used to determine what a plumber charges for a house call. $40 is a fixed charge and h is the number of hours spent at the house. What does the plumber charge for a job that takes 5 hours?!??
Ok. first replace h as 5: $60x5+$40 then simplify: 300+40=340 Your answer is $340
Your answer will be $340. Replace h with 5. 60*5+40. 300+40. $340.
