Question

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. What’s the unit price at Grocery Mart? What is the unit price at the Food Market? Based on price, which is the better value option?

Answer 1

To find the better value based on price for cereal on sale, compare unit prices: Grocery Mart's unit price is $2.50 per box, while Food Market offers a lower unit price of $2.25 per box, making Food Market the better option.

Step-by-step explanation:

The unit price at Grocery Mart for the cereal on sale is calculated by dividing the total cost by the number of boxes. So, for 4 boxes for $10, we divide $10 by 4, which gives us a unit price of $2.50 per box. Meanwhile, at Food Market, the cereal is on sale for $2.25 a box without any need for further calculation to find the unit price.

Comparing the two unit prices, the value option based on price alone is clearer. The cereal at Food Market is less expensive by $0.25 per box than the cereal at Grocery Mart. Therefore, to get the better value based on price, you would want to purchase the cereal from Food Market.
