21) A coffee shop blends 2 kinds of coffee, putting in 2 parts of a $0.33 pound grade to 1 part of a $0.24 grade. If the mixture is changed to 1 part of the $0.33 grade to 2 parts of the less expensive grade, how much will the shop save in blending 100 pounds?

$0.90
$1.00
$3.00
$8.00
$9.00

Explanation

Mixture 1
$0.66 + $0.24 = $0.90 for 3 pounds or $0.30/pound

Mixture 2
$0.33 + $0.48 = $0.81 for 3 pounds or $0.27/pound

The shop will save $0.03 per pound or $3.00 for 100 pounds.
