Question

At Plumbers “R” Us, the cost of the service call is $50 for him to show up at your house, plus an additional $ 15 per hour

PLS GIVE INDEPENDENT VARIABLE AND DEPENDENT

Answer 1

15h + 50

Step-by-step explanation:

Lets use "h" for hours.

50 is left alone and added at the end since its just one fee. Now since 15 is per hour and we don't know how long the plumber will be there we need a variable so 15h.
