Answer:
B. Food market
Step-by-step explanation:
You typically buy all of your groceries at Grocery Mart. This week, your favorite cereal is on sale there, 4 boxes for $10. At Food Market, where you don’t typically shop, the same cereal is on sale for $2.25 a box. Based on price, which is the better value option?
A.Grocery Mart
B. Food Market
