Question

A bowl contained 13 red and brown M&M's. there was one more red m&m than brown m&m. How many of each color are in the bowl ?

Answer 1

7 red M&M's and 6 brown M&M's.

Answer 2

6 brown m&m.

7 red m&m.

Explanation:

Let B represent brown M&M's and R represent red M&M's.

We have been given that a bowl contained 13 red and brown M&M's. We can represent this information in an equation as:

`B+R=13...(1)`

We are also told that there was one more red m&m than brown m&m. We can represent this information in an equation as:

`R=B+1...(2)`

Upon substituting equation (2) in equation (1), we will get:

`B+B+1=13`

`2B+1=13`

`2B+1-1=13-1`

`2B=12`

`(2B)/(2)=(12)/(2)`

`B=6`

Therefore, there are 6 brown m&m.

Upon substituting
`B=6` in equation (2), we will get:

`R=B+1`

`R=6+1`

`R=7`

Therefore, there are 7 red m&m.
