Question

how to solve measurement a pool that holds 320 cubic feet of water is 84 percent filled to capacity. another pool that hold 400 cubic feet of water is 82.5 percent filled to capacity. which pool contains more water? how much more?

Answer 1

Find 100%

first pool
320=0.84 times whole
divide both sides by 0.84
380.95=whole

second is
400=0.825 times whole
divide both sides by 0.825
484.848484=whole

how much more

484.848484-380.95=103.89

2nd pool holds 103.89 ft³ more water
