You went to Best Buy to purchase a new computer. You have a coupon for 20% off of the price. Best Buy is running a promotion where an additional 15% discount is given at
the register. If the computer costs $1099, how much will you pay after the discounts?

$714.35

Step-by-step explanation: First, you have a coupon for 20% off. Next, Best Buy also have a promotion discount for an additional 15% off. After you add all the discounts, you will have 35% off. 35% of 1099 is 384.65, so you will take 384.65 off of the original price, 1099. 1099-384.65 is equal to $714.35

both equations and proportions are better.
