Question

A bakery sold 101 cupcakes in one day. The head baker predicted he would sell 81 cupcakes that day. What was the percent error of the baker's prediction? *

Answer 1

Answer:

19.8% is the percent error of the baker's prediction.

Step-by-step explanation:

We are given the following in the question:

Total number of cupcakes sold in 1 day = 101

Predicted number of cupcakes sold = 81

We have to find the percent error of the baker's prediction.

Percentage error =

$=\dfrac{\text{Actual value - Predicted value}}{\text{Actual values}}\times 100\%$

Putting values, we get

$=\dfrac{101-81}{101}\times 100\%\\\\=19.8\%$

Thus, 19.8% is the percent error of the baker's prediction.
