Best buy is having a sale of 25% off all their computers. The original price on the computer was $1500 but there is a 8% shippin
skelet666 [1.2K]

Answer:

By 19% the computer was less than the original price  

Step-by-step explanation:

The original price on the computer was $1500

Discount is 25%= 0.25

Discount amount = 1500 * 0.25 = 375

Discounted price = 1500 - 375 = 1125

Now 8% shipping cost to discounted price

8% = 0.08

Shipping cost = 1125 * 0.08 = 90

cost of computer with shipping cost = 1125 + 90 = 1215

Percentage less = (original cost - cost of computer now ) / original cost

= \frac{1500- 1215}{1500}=0.19

To get percentage we multiply by 100

0.19 * 100 = 19%
