Question

A 12 ounce box of cereal cost $.84 how many ounces should be in a box marked $.49

Answer 1

Answer: 7

Explanation:

Rule of 3. Let's put the ounces on the left side and the price on the right side.

`(12)/(x)=(0.84)/(0.49)\\`

`x=((12)(0.49))/(0.84) \\x=7 ounces`

Answer 2

7 ounces

Explanation:

if 12 ounces is $0.84, that means it is $0.07 per ounce. if you have $.49, you divide .49 and 0.07 and you will get 7 ounces
