Question

Mason used a 30% coupon to buy a new computer. After the discount, the cost of the computer was $728.

Answer 1

The original price of computer is $ 1040

Solution:

Given that, Mason used a 30% coupon to buy a new computer

After the discount, the cost of the computer was $728

To find: original price of computer

From given question,

price after discount = $ 728

discount = 30 % of original price

Let "x" be the original price of computer

price after discount = original price - discount price

$728 = x - 30 \% \text{ of } x$

Let us solve the above expression for "x"

$728 = x - \frac{30}{100}x\\\\728 = x(1 - \frac{30}{100})\\\\728 = x (1 - 0.3)\\\\728 = x (0.7)\\\\x = \frac{728}{0.7}\\\\x = 1040$

Thus original price of computer is $ 1040
