Hello!
The regular price of the computer is $1,049.00. The store offers a 20% discount on this price.
A discount is a deduction from the price of something -- you save money.
In this case, the discount is 20%. We must find out how much it is worth, and then subtract that from the price of the computer.
To do this, convert the percentage to a decimal by dividing it by 100, then multiply the cost by the decimal, and finally SUBTRACT it.
20% ÷ 100 = 0.20
1,049 × 0.20 = 209.8
1,049 - 209.8 = 839.2
The cost of the computer (after the discount) is now $839.20.
Next, 5.25% sales tax is added onto the discounted price.
Sales tax is money collected by the government, so it is ADDED onto the price of an item. Simply repeat the steps we took to find the discount, but ADD instead of subtracting.
5.25 ÷ 100 = 0.0525
839.2 × 0.0525 = 44.058
The sales tax is $44.058. Add:
839.2 + 44.058 = 883.258
This can be rounded to 883.26.
ANSWER:
The total cost of the computer is $883.26.
