04.01)which unit rate is the lowest price per ounce? choice a: 15 ounces of chocolate chips for $2.49 choice b: 20 ounces of chocolate chips for $3.32 choice a choice b the unit rates are equal. the unit rates cannot be determined.

The answer choice below (or above) me is correct I beleive I just wanted to show proof.

15 ÷ 249 = 0.06024096

20 ÷ 332 = 0.06024096

As you can see both numbers are equal and if you round it the unit rate will be 0.06¢ (maybe im not sure if you'll have to change the 15 since we moved the decimal in 2.49)
