Question

If I bought a Computer for $1,500.00
and used my 75% off coupon. How
much was the computer originally?

Answer 1

Answer:

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

Step-by-step 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 % = $\dfrac{\textrm market price - \textrm selling price}{\textrm market price}$ × 100

Or, 75 % = $\dfrac{\textrm x - \textrm 1500}{\textrm x}$ × 100

Or, $\frac{75}{100}$ = $\dfrac{\textrm x - \textrm 1500}{\textrm x}$

Or, $\frac{1500}{x}$ = 1 - $\frac{75}{100}$

Or, $\frac{1500}{x}$ = $\frac{100 - 75}{100}$

Or, $\frac{1500}{x}$ = $\frac{25}{100}$

Or, x = $\frac{150000}{25}$

∴  x = $ 6,000

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