Final answer:
The grocery outlet has a better price for pineapple as it is cheaper per can.
Step-by-step explanation:
To determine which store has a better price for pineapple, we need to compare the cost per can at each store. At the grocery outlet, three cans of pineapple cost $2.25, so the cost per can is $2.25 / 3 = $0.75. At the save market, six cans of pineapple cost $4.80, so the cost per can is $4.80 / 6 = $0.80. Therefore, the grocery outlet has a better price for pineapple as it is cheaper per can.
