Answer:
$ 0.38
Step-by-step explanation:
128 x 4.8 = 614.4
A 128 ounce jug costs $6.14
64 x 5.1 = 326.4
A 64 ounce jug costs $3.26
Two jugs of 64 onces would be equal to the 128 ounces, so double the cost of the 64 ounce.
$3.26 x 2 = $6.52
Then subtract the difference
$6.52 - $6.14 = $0.38
9514 1404 393
