Question

The price of a TV after a 20% discount is $620, what was the price before the discount?​

Answer 1

Answer:

The original prince is: $775            

Step-by-step explanation:

• As the discount is 20%.

As we know that

• 100% - 20%  = 80% = 80/100 = 0.8

The price after 20% discount = Discounted price = $620

We have to find the original price before the discount.

using the formula

(Discounted price) = (100 percent - discount percent) x (original price)

          $620            = (100% - 20%) x (original price)

          $620            = (80%) x (original price)

          $620             = (80/100) x (original price)

          $620              = (0.8) x (original price)

so

original price = $620/0.8

                      = $775

Therefore, the original prince is: $775
