Abakery sold 114 cupcakes in one day. the head baker predicted he would sell 94 cupcakes that day. what was the percent error of the baker's prediction?

17.54%

Step-by-step explanation:

The value of cupcakes sold by the Baker = 114

Predicted amount of cupcakes he thinks he will sell = 94

To find the percent prediction error;

First we need to get the margin error in value;

Value error in cupcakes = amount of cupcakes sold - amount predicted

= 114-94

= 20

%error = value error in cupcake/amount of cupcakes sold × 100%

%error = 20/114×100%

%error in prediction = 17.54%
