Question

You are preparing small and large cupcakes for the school bake sale. If you will need 1/3 a spoon of sugar for each small cupcake, and 1/2 a spoon of sugar for the large cupcake.if you need to make 30 small cupcakes and 20 large cupcakes, and you have a total of 21 spoons of sugar. Is this enough to make your cupcakes?

Answer 1

Yes as the small cupcakes would need 10 spoons (=1/3 of 30) where the large cupcakes would need 10 spoons of sugar (=1/2 of 20).

Explanation:

30 x 1/3 = 10

30 x 1/2 = 10

10+10 =20

= 20 spoons of sugar makes 10 of each size cupcakes, so 21 spoons mentioned in the question would be enough.

Answer 2

yes

Explanation:

1/3x30 is 10 which would be 10 spoons

1/2x20 is also 10 which would be another 10 spoons

10+10 equals 20

you have 21 spoons which means that you will have enough spoons of sugar to make all 50 cupcakes
