Question

1. Music Systems, Inc. allows a 10% discount if a purchase is paid for within 30 days. An additional 5% discount is given if the purchase is paid for within 15 days. Brent Goodson buys a sound system that originally cost $360. If he pays the entire amount at the time of purchase, how much does he pay for his system after the successive discounts?

Answer 1

$306

Explanation:

15/100 = x/360

This is just a proportion, so you would multiply 360 time 15 which is 5,400 then divide that by 100, leaving you with $54. Meaning, he saved $54. If you take her saved $54 away from the original price of $360, you are left with $306 as his final price to pay.
