Answer 1

8

Explanation:

Noah made 125% of cookies he was asked to make.

64(required) * 1.25=80 cookies he made.

He sold 90% of the 80 cookies

80*.9=72. 8 cookies left over

Answer 2

`There~were~8~cookies~left~after~the~bake~sale.`

Explanation:

`According~to~the~question,~noah~was~assigned~to~make~64~cookies`
`for~the~bake~sale~he~made~125`%
`of~that~number`
`90`%
`cookies~he~made~were ~sold .`

`125`%
`is~written~in~the~decimal~form:`

`(125)/(100)=1.25`

Total number of cookies made by noah:

`1.25` ×
`total~number~of~cookies~cookies ~assigned ~to ~make .`

`Now,~we~put~it~in~all~the~values~of~the~above:`

`=1.25` ×
`64`

`=80`

Now, for the second part As given:

`90`%
`of ~the ~cookies ~he ~made~ were ~sold .`

`90`%
`written~in~the~decimal~form:`

`=(90)/(100)`

`=0.90`

The number of cookies that were sold:

`=0.90` ×
`Total~ number~ of~ cookies~made~by~noah:`

`=0.90` ×
`80`

`=72`

Thus, :

`Number ~of~ cookies~ left =Total~ number~ of ~cookies~made`
`by~noah-Number`
`of ~cookies~that~ were ~sold .`

`=80-72`

`=8`

So, the answer to this question is :

`There~were~8~cookies~left`
`after~the~bake~sale.`
