Answer
So the unit rate for the nearest cent per ounce for each size is 0.24 : 0.19.
Step-by-step explanation:If 16oz cost 3.89, then 1 oz costs 3.89 ÷ 16 = 0.243125 ≈ 0.24
If 32oz cost 5.98, then 1 oz costs 5.98 ÷ 32 = 0.186875 ≈ 0.19
So the unit rate for the nearest cent per ounce for each size is 0.24 : 0.19.
