9. 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? 4 six-packs 6 four-packs

If the shopper buys 4 six-packs, that would provide \( 4 \times 6 = 24 \) rolls at a total cost of \( 4 \times 5.28 = \$ 21.12 \). On the flip side, purchasing 6 four-packs gives \( 6 \times 4 = 24 \) rolls, costing \( 6 \times 3.40 = \$ 20.40 \). It seems buying 6 four-packs would save the shopper some cash while still getting the desired number of rolls! In the world of grocery shopping, being strategic about package sizes can lead to significant savings. Always take the time to compare unit prices! Remember, just because a package looks like a better deal doesn't mean it actually is. Do the math and save those pennies, because they add up to dollars in the long run!
