A12-pack of 8-ounce juice boxes cost $5.40 how much would an 18-ounce of juice boxes cost if it is a proportionate price? ?
a. $9.40 b. $8.10 c $3.60 d. $12.15

The correct answer is B. 18 packs of juice boxes would cost $8.10.

Step-by-step explanation:

To get the answer to this question we must calculate the cost per unit of each pack of juices: if 12 packs cost $ 5.40, each unit will be worth $ 0.45 (5.4 / 12), therefore, to know the cost of 18 packs we must multiply the price per unit ($ 0.45) for the total amount of packs (0.45 x 18), which gives a total of $ 8.10. This, therefore, would be the price for the 18 packs.
