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
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.
