Answer 1

A box of oat cereal cost lees than a box of rice cereal cost per ounce.

Explanation:

Given:

15 oz of oat cereal cost = $3.90

11 oz of rice cereal cost = $3.30

We need to find the which box of cereal cost less per ounce.

Solution.

First we will find cost of 1 oz of oat cereal.

Now we know that;

15 oz of oat cereal cost = $3.90

1 oz of oat cereal cost = cost of 1 oz of oat cereal.

By Using Unitary method we get;

cost of 1 oz of oat cereal =
`(3.90)/(15) = \$0.26`

Now we will find cost of 1 oz of rice cereal.

Now we know that;

11 oz of rice cereal cost = $3.30

1 oz of rice cereal cost = cost of 1 oz of rice cereal.

By Using Unitary method we get;

cost of 1 oz of rice cereal =
`(3.30)/(11) = \$0.3`

Now from above we can see that cost of 1 oz of oat cereal is $0.26 and cost of 1 oz of rice cereal is $0.3.

Hence we say that, A box of oat cereal cost lees than a box of rice cereal cost per ounce.
