Question

Elena's mother's painting service charges $10 per job and $0.20 per square foot. If she earned $50 for

painting one job, how many square feet did she paint at the job? Write an equation and solve.³

Answer 1

so the total charge for the job was $50,

so all we need is the finding of x (# of square feet):

10 + 0.20x = 50

Explanation:

Solving for x:

0.20x = 50 - 10

0.20x = 40

x = 40/0.20

x = 200 square feet

hope it helps!
