Ms.Javori decides to make a total of 45 cupcakes for a fun Friday celebration! 1/3 of the cupcakes had chocolate frosting and the rest had vanilla frosting. out of the cupcakes that have vanilla frosting, 2/5 of them also had sprinkles and the others had no sprinkles. how many cupcakes had vanilla frosting but did not have any sprinkles?
we have that
1) total 45 cupcakes
2) 1/3 of the cupcakes had chocolate frosting -----> (1/3)(45)=15
3) 2/3 0f the cupcakes had vanilla frosting -----> (2/3)(45)=30
4) 2/5 of 30 had sprinkles------> (2/5)(30)=12
5) 3/5 of 30 had no sprinkles ------> (3/5)(30)=18
therefore
the answer is 18
