Chris needs to fill his son's sandbox that is 5 feet by 7 feet. He wants to buy sand bags to fill the sand 2 feet deep. He compares the prices found for sand at two different stores,
Store X: 30 lb bag for $3
Store Y: 32 lb bag for $4
Part A
What is the unit rate that Store x is selling for?
Ibs/dollar
What is the unit rate that Store Y is selling for?
Ibs/dollar
Part B
Which store is offering the better price?
Part
Chris finds that it takes 100 pounds of sand to fill 1 cubic foot. Using the better priced store, compute how much it will cost him to
purchase enough sand to fill the sandbox. Use the volume formula, V = 1 x W xh, to determine your answer.
