Solution

total weight of tub and water = 875.7 pounds

bathtub contains 60 gallons of water

that is weight of water = 60 * 8.345 = 500.7 pounds

c) weight of tub when there is no water is 875.7 - 500.7 = 375 pounds

d) weight of tub and water = 566.935 pounds

setting up a proportion

875.7 / 60 = 566.935 / x

x = 566.935*60 / 875.7

x = 38.84 gallons

or 39 gallons ( round off)
