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?\n$0.38\n$0.54\n$4.27\n$6.14
Answer
Explanation:
Step1: Calculate cost of two 64 - ounce cartons
The cost of one 64 - ounce carton with a unit price of 5.1 cents per ounce is $64\times5.1$ cents. The cost of two cartons is $2\times64\times5.1= 2\times326.4 = 652.8$ cents.
Step2: Calculate cost of 128 - ounce jug
The 128 - ounce jug has a unit price of 4.8 cents per ounce. So its cost is $128\times4.8=614.4$ cents.
Step3: Calculate the savings
The savings is the difference between the cost of two cartons and the cost of the jug, which is $652.8 - 614.4=38.4$ cents. Since 1 dollar = 100 cents, in dollars, it is $\frac{38.4}{100}=0.384\approx0.38$ dollars.
Answer:
$0.38$ (corresponding to the first option)
