Question

Siobhan is preparing for her beach party in January. She needs to buy 120 cubic feet of sand to cover her garage floor. Sand comes in bags of 10 cubic feet. Each bag of sand costs $7.50, including tax. How much money does Siobhan need to turn her garage into a beach?

Answer 1

She needs 120 cu ft.
Each bag has 10 cu ft.

(120 cu ft)/(10 cu ft per bag) = 12 bags

She needs to buy 12 bags.

12 bags * $7.50 per bag = $90

Answer: $90
