Answer 2

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 - (30)/(100)x\\\\728 = x(1 - (30)/(100))\\\\728 = x (1 - 0.3)\\\\728 = x (0.7)\\\\x = (728)/(0.7)\\\\x = 1040`

Thus original price of computer is $ 1040
