A shopper needs 48 hot dogs. The store sells identical hot dogs in 2 different sized packages. They sell a six pack of hot dogs for $2.10, and eight-pack of hot dogs for $3.12. Should the shopper buy 8 six-pack, or 6 eight-packs? Explain your reasoning.

Eight six-pack. 8 x 2.10 is $16.80, while 6 x 3.12 is 18.72.

6-pcs pack = $2.10

Hot dogs needed = 48

Number of 6-pcs = 48 : 6 = 8

Total cost = $2.10 x 8 = $16.80

8-pcs pack = $3.12

Hot dogs needed = 48

Number of 8-pcs pack = 48 : 8 = 6

Total cost = $3.12 x 6 = $18.72

The shopper should buy the 6 pcs pack because it is cheaper.
