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
[tex]\text{Cost per ounce}=\dfrac{\text{Total cost}}{\text{Number of ounces}}[/tex]
Using this formula, we get
Per ounce cost of small container [tex]=\dfrac{3.87}{48}[/tex]
[tex]=0.080625[/tex]
[tex]\approx 0.08[/tex]
Per ounce cost of larger container [tex]=\dfrac{6.42}{128}[/tex]
[tex]=0.05015625[/tex]
[tex]\approx 0.05[/tex]
Since, 0.08 > 0.05 therefore, the per ounce cost of larger container is less.
