Question

If I bought a Computer for $1,500.00

and used my 75% off coupon. How
much was the computer originally?

Answer 1

The original price of the computer is $ 6,000 .

Explanation:

Given as :

The selling price for the computer = $ 1,500.00

The discount coupon = 75 %

Let the original price or market price of computer = $ x

Now,

Discount % =
`(\textrm market price - \textrm selling price)/(\textrm market price)` × 100

Or, 75 % =
`(\textrm x - \textrm 1500)/(\textrm x)` × 100

Or,
`(75)/(100)` =
`(\textrm x - \textrm 1500)/(\textrm x)`

Or,
`(1500)/(x)` = 1 -
`(75)/(100)`

Or,
`(1500)/(x)` =
`(100 - 75)/(100)`

Or,
`(1500)/(x)` =
`(25)/(100)`

Or, x =
`(150000)/(25)`

∴ x = $ 6,000

Hence The original price of the computer is $ 6,000 . answer
