What is the price per oz to the nearest cent of the least expensive: 15 oz for $4.56 or 25 oz for $5.98?

Question 4 options:

0.28

0.25

0.3

0.24

For the first one the price per ounce is:

$4.56/15oz=0.304 dollars per ounce, which rounds to 0.3

For the second:

$5.98/25oz=0.2392 dollars per ounce, which rounds to 0.24

The second is the cheapest price per ounce and rounds to $0.24/oz so 0.24 is the answer
