Question

A plumber comes to the house. He charges $50 for an initial fee plus $30 per hour. The equation C=50 +30h represents the relationship between the quantities in this situation, where C is the cost in dollars for the job and h is the number of hours.

1. Name a possible solution to this equation C=50 + 30h. What does the solution mean?

Answer 1

h = C-50/30

Explanation:

50+30h=C

50+30h-50=C-50

30h=C-50

30h/30 = c/30 - 50/30

h = C-50/30
