Question

Abby uses 1 gallon of paint to cover 200 square feet of ceiling. the ceiling she is painting is approximately 85 square feet. write and solve a proportion to find the number of gallons of paint she needs to cover 885 square feet

Answer 1

1 gallon / 200 ft^2 = x gallons / 885ft^2

cross multiply (200 • x, 1 • 885)

200x = 885
