Question

how can you use a rate to compare the cost of two boxes of cereal that are different sizes

Answer 1

I know of one way, but I'm not sure if this is what you're looking for. Let me give an example to help:

I have 2 cereal boxes. One that weighs 10oz and cost $5, and another that weighed 6oz and cost $2. To compare them, you'd create ratios. I'll do oz/$

$\frac{10}{5}$ & $\frac{6}{2}$
Simplify. You should get 2 and 3. Now we know that the 10oz for $5 is a better deal than 6oz for $2. 

Answer 2

Answer:

Step-by-step explanation:

I think it is quite simple

Step 1. Find out the cost per ounce.

Step 2. Divide the cost of the box by the number of ounces.

hope this will find you well!
