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

= 
To get percentage we multiply by 100
0.19 * 100 = 19%
