The original price of the cake was $14.We were told that it was discounted 15%. Recall, percentage is expressed in terms of 100. Thus, the amount by which it was discounted is
15/100 x 14
= 2.1
To get the new price, we would subtract the amount by which it was discounted from the original price. Thus, the new price of the cake is
12 - 2.1
= 11.9
The new price of the cake is $11.9
