9 cupcakes will have vanilla icing.
Joakim total amount of cupcakes = 30
Total amount of cupcakes used for mint icing = 1/5 of 30 [cupcakes] otherwise expressed as 1/5 x 30
= 1/5 x 30
= 1 x 30 ÷ 5
= 30 ÷ 5
= 6
Thus, 1/5 of 30 cupcakes = 6
Total amount of cupcakes used for chocolate icing = 1/2 of 30 [cupcakes] and can be expressed as 1/2 x 30
= 1/2 x 30
= 1 x 30 ÷ 2
= 30 ÷ 2
= 15
Therefore, 1/2 of 30 cupcakes = 15
To determine the amount of cupcakes that will contain vanilla icing, the total value of the addition of the total amount of cupcakes used for both mint icing and chocolate icing would be derived, and subtracted from the total given cupcakes.
Therefore, Total amount of cupcakes used for both mint icing and chocolate icing respectively =
1/5 of 30 [6] + 1/2 of 30 [15]
= 6 + 15
= 21
Therefore, the total cupcakes to be used for vanilla icing will be:
30 – 21
= 9
Hence, 9 cupcakes would be used for vanilla icing.
