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

Find out the cost per ounce.

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

every cereal box has gift inside

Unit pricing. It is probably listed on the shelf but you can do it yourself anyway.

Both boxes will have the mass of cereal contained in each. Say box A is 1 kilogram and box B is 2 kilograms
Say box A costs 1 dollar and box B costs 1.50 dollars
then
Box A costs 1 dollar per kilogram and box B costs 1.50/2 = 0.75 dollars per kilogram

Obviously box B costs less per kilogram.

so u do all of this but what is the answer i need the answer now help me i need help this class is hard and no one helps help me now i need help with thus stupid math help with the math i need a A in math help !!!!!!!!!!!!!!!!!!!!!!!!.

To compare the costs of two boxes of cereal that are different sizes, you can use a rate called "cost per unit." Here's how you can do it:

1. Determine the cost and size of each box of cereal:
- Let's say box A costs $4 and has a size of 500g.
- Box B costs $6 and has a size of 750g.

2. Calculate the rate of each box:
- For box A: Divide the cost by the size. $4/500g = $0.008/g.
- For box B: Divide the cost by the size. $6/750g = $0.008/g.

3. Compare the rates:
- The rate for box A is $0.008/g.
- The rate for box B is $0.008/g.

4. Analyze the rates:
- As both boxes have the same rate of $0.008/g, we can conclude that the cost per gram (unit) of both boxes is the same.

Therefore, in this case, based on the cost per unit, box A and box B have the same price.

You can just simply divide the number of ounces

You can, find out the unit rate or the cost per ounce. Then, you can divide the cost of the first box / box #1 by the number of ounces in that box and do the same thing with the other box / box #2. I hope this helps!

use maths

Thank You if i copy that.
