Question

The unit price of a 128-ounce jug of milk is 4.8 cents per ounce. A 64-ounce carton of milk has a unit price of 5.1 cents per ounce. Approximately how much money is saved by purchasing a larger jug instead of two cartons? $0.38 $0.54 $4.27 $6.14

Answer 1

Price of 128 ounces jug = 4.8 cents/ounce

$= 128 \times 4.8$

$= 614.4 \: cents$

1 dollar($)=100 cents

$= \frac{614.4}{100}$

$= 6.144$

Price of 64 ounces jug = 5.1 cents/ounce

$= 64 \times 5.1$

$= 326.4 \: cents$

$= 3.264$

Two such jugs will be;

$= 3.264 \times 2$

$= 6.582$

Difference between one two 64 ounce of jug and one 128 ounce of jug;

$6.582 - 6.144$

$= 3.84$

Money saved by purchasing one 128 ounce of jug rather than two 64 ounce of jug is $3.84
