Answer:
Rules to find the original price given the sale price and percent discount
First consider the unknown original price as ‘x’.
Then consider the rate of discount.
To find the actual discount, multiply the discount rate by the original amount ‘x’.
To find the sale price, subtract the actual discount from the original amount ‘x’ and equate this to given sale price.
Solve the equation and find the original amount ‘x’.
Example 1:
A desk is being sold at a 36% discount. The sale price is $496. What was its original price?
Solution
Step 1:
Let the original price be = x
Discount rate = 36%
Step 2:
Discount = 36% of x = 0.36 × x = 0.36x
Sale price = Original price − Discount = x − 0.36x = 0.64x
Step 3:
Sale price = $496 = 0.64x
Solving for x
x = 4960.64= $775
So, original price = $775
