Answer:

Part A; 9

Part B; 14%

Step-by-step explanation:

Part A;

Knowing that pumpkin cupcake = 6

Total = add all the cupcake which is 2+1+5+6 = 14

Cross multiply

[tex]\frac{6}{14}=\frac{x}{21}[/tex]

6*21 = 126

126/14 = 9

Hence, Next 21 cupcakes sold, 9 cupcake will be pumpkin cupcake

-------------------------------------------------------------------------------------------------------------

Part B;

The probability of a chocolate cupcake being sold would be equal to the amount of chocolate cupcakes divided by the total number of cupcakes.

= 2/(2+1+5+6)

= 2/14

= 1/7.

We convert 1/7 to a percent.

When rounded to the nearest whole percent, we get the probability as 14%.
