A bakery sold 103 cupcakes in one day. The head baker predicted he would sell 83 cupcakes that day. What was the percent error of the baker's prediction? A. 24.10% B. 20% C. 80.58% D. 19.42%

Option D: 19.42%

Step-by-step explanation:

If the bakery predicted that he would sell 83 cupcakes and the number of cupcakes that were sold was 103, we can calculate the percent error making the difference between the number of cupcakes he made and the number of cupcakes he predicted, and then dividing the result by the number of cupcakes he made:

error = (103 - 83) / 103 = 20/103 = 0.1942 = 19.42%
