Question

A shopper needs 24 sandwich rolls. The store sells identical rolls in 2 differently sized packages. They sell a six-pack for $5.28 and a four-pack for $3.40. Should the shopper buy 4 six-packs or 6 four-packs? Explain your reasoning.

Answer 1

Answer:

If the shopper buys 4 six-packs it will cost him-

4 x 5.28$ = 21.12$

If the shopper buys 6 four-packs it will cost him-

6 x 3.40$ = 20.4$

Hence, he should buy 6 four-packs as it will cost him less by 0.72$.
