backpack discounted 10% on sale for $37.80
To calculate the original price of the backpack before the discount, you can use the formula:
Original Price = Sale Price / (1 - Discount Percentage)
In this case, the sale price of the backpack is $37.80 and the discount percentage is 10%.
Step 1: Convert the discount percentage to its decimal form by dividing it by 100.
10% / 100 = 0.10
Step 2: Subtract the discount amount from 1.
1 - 0.10 = 0.90
Step 3: Divide the sale price by the result from step 2 to get the original price.
$37.80 / 0.90 = $42
Therefore, the original price of the backpack before the discount was $42.
