To paint a house, a painting company charges a flat rate of $500 for
supplies, plus $50 for each hour of labor.
a. how much would the painting company charge to paint a house that
needs 20 hours of labor? a house that needs 50 hours?

For 20 hours it would be $1,500 and for 50 hours it would be $3,000.

Step-by-step explanation:

The equation for this problem would be y=50x+500.

Y is the total charge and x is the amount of hours. Plug in 20 and 50, and then you have your answer.
