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
[tex]728 = x - 30 \% \text{ of } x[/tex]
Let us solve the above expression for "x"
[tex]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[/tex]
Thus original price of computer is $ 1040
