A. 7.5%
B. 8%
C. 8.5%
D. 9%

Answer 1

To find the percentage of a discount, subtract the sale price from the original price, divide by the original price, and multiply by 100. The discount on the air conditioner is 7.5%.

Step-by-step explanation:

The question is asking us to calculate the percentage of discount given on an air conditioner. The original price of the air conditioner is $280 and the sale price is $259. To find the discount percentage, we need to subtract the sale price from the original price and then divide by the original price. Finally, we multiply by 100 to convert it to a percentage.

Here is the calculation:

1. Find the amount of discount: $280 - $259 = $21.
2. Divide the discount by the original price: $21 / $280.
3. Multiply the result by 100 to get the percentage: ($21 / $280) × 100.

Performing these calculations gives us:

($21 / $280) × 100 = 7.5%

Therefore, the percentage of discount for the air conditioner is 7.5%, which corresponds to option A.
