Answer:
77.5%
Step-by-step explanation:
The question gives the first laptop price, the first discount and the subsequent discount. This is therefore how we will go about obtaining the total percentage discount;
Price of New Laptop = $1500
New Price after first discount = $1500 - (10% of $1500) = $1500 - $150 = $1350
Then an additional 75% discount gives: $1350 - (75% of $1350) = $1350 - $1012.50 = $337.50
Now, the total discount is the difference in the first laptop price ($1500) and this current price: $1500 - $337.50 = $1162.50
The total percentage discount = × 100% =
× 100% = 77.5%
