mason used a 30% coupon to buy a new computer. after the discount, the cost of the computer was $728. determine the original price of the computer . show your work . calculate how much money Mason saved by using the coupon . show your work .

Answer 1

Let's call x to the original price.

Given that Mason used a 30% coupon, then he paid 0.3x dollars less.

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

x - 0.3x = 728

0.7x = 728

x = 728/0.7

x = 1040

The original price of the computer was $1040

Mason saves 30% of $1040, which is computed as follows:

`1040\cdot(30)/(100)=312`

Mason saves $312
