Answer 2

Answer:

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

Step-by-step explanation:

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

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

$\frac{125}{100}=1.25$

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:

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

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

$=\frac{90}{100}$

$=0.90$

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 :

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