Question

A box of Cereal X contains 36 ounces and costs $ 4.99. A box of Cereal Z contains 30 ounces and costs $ 4.50. Which cereal is the better buy ?

4.99 / 36 = $0.14 per ounce

4.50 / 30 = $0.15 per ounce

Answer 2

Thank you.

Answer 3

You're welcome.

Answer 4

To determine which cereal is the better buy, we need to calculate and compare their unit prices. The unit price is the cost of one ounce of cereal.

For Cereal X, the unit price can be calculated as:
Unit Price of Cereal X = Cost of Cereal X / Number of Ounces in Cereal X
Unit Price of Cereal X = $4.99 / 36 ounces

For Cereal Z, the unit price can be calculated as:
Unit Price of Cereal Z = Cost of Cereal Z / Number of Ounces in Cereal Z
Unit Price of Cereal Z = $4.50 / 30 ounces

Now let's calculate the unit prices for both cereals:

Unit Price of Cereal X = $4.99 / 36 ounces ≈ $0.139 / ounce
Unit Price of Cereal Z = $4.50 / 30 ounces ≈ $0.150 / ounce

Comparing the unit prices, we can see that Cereal X has a lower unit price ($0.139 per ounce) compared to Cereal Z ($0.150 per ounce). Therefore, Cereal X is the better buy as it has a lower cost per ounce.
