Answer 3

this problem is very similar to the previous problem in that you have to find unit costs.
There are 2 different stores. Their unit prices are different. Find the unit price for each store in exactly the same way we used last time:
Package cost
unit price = --------------
package weight

Answer 4

so what exact numbers will I need to divide

Answer 6

"At Jim`s Super Sales Club Store, boxes of breakfast cerel weigh 2 pounds 10 ounces and cost $4.20 each." This translates into

$4.20
------------------------------
2(16)+10 ounces

since 1 lb = 16 oz.

Now find the unit price for the other store in the same manner.

Answer 7

so $4.20/ 42?

Answer 8

Yes, and do the same thing for the other store's price.
