Question

The school sells 240 cookies. ¼ of the cookies had chocolate chips, ½ of the remaining cookies had raisins, and the rest were peanut butter. How many cookies were peanut butter?

Answer 1

90 peanut butter

Explanation:

Total number of cookies
`=240`

Number of chocolate cookies
`=(1)/(4)(240)=60`

Therefore,

Number of remaining cookies
`=240-60=180`

Number of raisins
`=(1)/(2)(180)=90`

So,

Number of peanut butter
`=180-90=90`
