Answer:
4 6-packs cost $14.40; 8 of them cost $28.80; the unit rate (one can) is $3.60
Step-by-step explanation:
The given amount, $7.20 is the price for two 6-packs, so the price for 4 6-packs is that number ($7.20) times 2 which equals $14.40. Multiply this number ($14.40) by 2 once more to get the price for 8 6-packs (this works because 4 x 2 is 8). Looking back at $7.20, we know that it is the price of two packs. Find the price of one pack, the unit rate, by dividing $7.20 by 2. $7.20 ÷ 2 = $3.60.
