At a school bake sale, a total of 40 cupcakes and muffins were sold. The total number of cupcakes sold was 12 more than the number muffins. How many cupcakes were sold at the bake sale?

my answer got deleted but it's a

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
