Question

An item is on sale for $100. If it was discounted by 20%, what was the original selling price?

Answer 1

Answer: The original price was  $125

Step-by-step explanation:

If an item is on sale for $100 and it was discounted by 20%  then we could set up an equation and solve for the original price.

Remember if there were 20% discount then 80% of the price will be left.

80% * x = 100    

0.8x =100

x = 125

Answer 2

Step-by-step explanation:

We have :

• Selling Price = $100

• discount = 20%

As we know

• Selling Price = Cost - Discount

Now we have

• Discount = 20%

Let cost be x

→ Selling Price = x - 20% of x

→ selling price = 80% of x

→ 80% of x = 100

→ 80/100 x = 100

→ x = 100 × 100 / 80

→ x = $ 125
