The amount saved is $0.80 or 80 cents.
Since Soil sells for 8 1/4 cents per pound, the coat for 100 pound sack will be:
= 8 1/4cents × 100
= 8.25 cents × 100
= 825 cents
Since 100 cents = $1
825 cents = 825/100
825 cents = $8.25
Since the 100 pound sack was bought for $7.45, the amount saved will be:
= $8.25 - $7.45
= $0.80
