A plumber charges $50 for every house call and an additional $70 for each hour of work. For one house call yesterday, the plumber earned $435.
Which equation can be solved to find the number of hours the plumber worked on the house call?
A.
B.
C.
D.
Let's assume the number of hours the plumber worked is represented by the variable "h".
The cost for the house call is a fixed amount of $50, and the cost for the hours of work is $70 per hour. Therefore, we can set up the equation:
50 + 70h = 435
The equation that can be solved to find the number of hours the plumber worked on the house call is:
B. 50 + 70h = 435
