Archy [21]

Answer:He should buy the six pack.

Step-by-step explanation:

The total number of hotdogs that the shopper needs is 48.

The store sells identical hot dogs in 2 differently sized packages. They sell a six pack hot dog for $2.10, and an eight pack of hot dog for $3.12.

If the shopper buys the six pack hot dog, he would need to buy 8 of it. The total cost would be

8 × 2.10 = $16.8

If the shopper buys the eight pack hot dog, he would need to buy 6 of it. The total cost would be

6 × 3.12 = $18.72

The 6 pack is cheaper than the eight pack. Therefore,

He should buy the six pack.
