Answer:

C.) 20%

Step-by-step explanation:

First we must calculate our total number of cookies:

25+15+10=50

This will be our denominator, our numerator in our fraction will be the amount of strawberry cookies (10):

[tex]\frac{10}{50}=\frac{1}{5}  =0.20[/tex]

Now we multiply our result by 100 to convert from decimal to percentage and so:

0.20 x 100 = 20%
