elena-14-01-66 [18.8K]

Consider the complete question is "A store has two different sizes of ice cream on sale this week. The smaller container costs $3.87 for 48 ounces. The larger container costs $6.42 for 128 ounces. which ice cream costs less per ounce?"

Given:

The smaller container costs $3.87 for 48 ounces.

The larger container costs $6.42 for 128 ounces.

To find:

Which ice cream costs less per ounce?

Solution:

We know that

\text{Cost per ounce}=\dfrac{\text{Total cost}}{\text{Number of ounces}}

Using this formula, we get

Per ounce cost of small container =\dfrac{3.87}{48}

                                                         =0.080625

                                                         \approx 0.08

Per ounce cost of larger container =\dfrac{6.42}{128}

                                                         =0.05015625

                                                         \approx 0.05

Since, 0.08 > 0.05 therefore, the per ounce cost of larger container is less.
