Answer: 12 cupcakes will get chocolate frosting
Step-by-step explanation: John started with 30 cupcakes and spresd mint icing on 1/5 of these. That means he did the following
Mint icing = 30 x 1/5
Mint icing = 6
That leaves him with a total of 30 minus 6 cupcakes which equals 24 cupcakes.
Next he spreads chocolate icing on half of the remaining, that is half of 24. That means he did the following;
Chocolate icing = 24 x 1/2
Chocolate icing = 12
Therefore 12 cupcakes will get chocolate frosting
