How can you use a rate to compare the costs of two boxes of cereal that are different sizes?

1 answer:

6 0

If you are given a unit rate (ex: $0.59 per ounce) then you can multiple this by the weight of the cereal to find the cost of the entire box. Do this for both boxes, and then compare the costs.

Hope this helps. I'm not sure that I'm on the right path, but I can help you further if you provide more details.

Good luck!

Annie has $18.00 to spend at the grocery store. She is going to buy bags of nuts that cost $5.70 each and one box of cookies tha

Tcecarenko [31]

Answer: She can buy up to 2 bags of nuts

Step-by-step explanation:

Hi, to answer this question we have to write an inequality:

The product of the number of bags of nuts bought (n) and the price per bag (5.70); plus the price of one box of cookies (4.25) must be less or equal to Annie's money (18).

5.70n +4.25 ≤18

Solving for x:

5.70n ≤18 -4.25

5.70n ≤13.75

n ≤13.75/5.70

n ≤2.41

n ≤2 (rounded)

She can buy up to 2 bags of nuts
