doors galore service charge is 40 and the hourly rate is 50

G&H charge is 60 and hourly rate is 40

write an eqation to represent the total cost y for x hours of labor by each repair company

Answer 1

All you need to do here is know where and how to plug in the numbers. In each equation, you'll have an initial fee, and an hourly fee, so your equation will be
y = i + hx, where i = the initial fee, and h = the hourly fee

So, after plugging them in, here's what you get:
Doors Galore: y = 40 + 50x
G&H: y = 60 + 40x
