Noah was assigned to mame 64 cookies for a bake sale. He made 125% of that number. 90% of the cookies he made were sold. How many of noahs cookies were sold after the bake sale

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

[tex]125[/tex]% [tex]is~written~in~the~decimal~form:[/tex]

[tex]\frac{125}{100}=1.25[/tex]

Total number of cookies made by noah:

[tex]1.25[/tex] × [tex]total~number~of~cookies~cookies ~assigned ~to ~make .[/tex]

[tex]Now,~we~put~it~in~all~the~values~of~the~above:[/tex]

[tex]=1.25[/tex] × [tex]64[/tex]

[tex]=80[/tex]

Now, for the second part As given:

[tex]90[/tex]% [tex]of ~the ~cookies ~he ~made~ were ~sold .[/tex]

[tex]90[/tex]% [tex]written~in~the~decimal~form:[/tex]

[tex]=\frac{90}{100}[/tex]

[tex]=0.90[/tex]

The number of cookies that were sold:

[tex]=0.90[/tex] × [tex]Total~ number~ of~ cookies~made~by~noah:[/tex]

[tex]=0.90[/tex] × [tex]80[/tex]

[tex]=72[/tex]

Thus, :

[tex]Number ~of~ cookies~ left =Total~ number~ of ~cookies~made[/tex] [tex]by~noah-Number[/tex] [tex]of ~cookies~that~ were ~sold .[/tex]

[tex]=80-72[/tex]

[tex]=8[/tex]

So, the answer to this question is :

[tex]There~were~8~cookies~left[/tex] [tex]after~the~bake~sale.[/tex]
