Answer:
The answer is D or 32oz for $3.00
Explanation:
You're trying to find how much it cost for just 1 ounce so divide the price by the ounces:
a. $ 1.25 ÷ 12 = $ .104 per ounce
b. $ 1.65 ÷ 16 = $ .103 per ounce
c. $ 2.15 ÷ 20 = $ .1075 per ounce
d. $ 3.00 ÷ 32 = $ .09375 per ounce
Option D is the cheapest per ounce of all four choices!
