1. Kara wants to buy a handbag that has a retail price of $789.95. She has a 15% coupon. If there is a 8.6% sales tax, how much will Kara spend on the handbag?
Discount = % (of) = 0.15(789.95)Discount = $118.49
Sale price = 789.95 -118.49 671.46
Answer: Kara spent $729.21 on the handbag.
Tax = % (of) = 0.086(671.46) Tax = $57.75
Total w/tax = 671.46 +57.75 $729.21

14. A truck traveling at a constant rate of 45 miles per hour leaves Inversetown. One hour later a car traveling at a constant rate of 60 miles per hour also leaves Inversetown traveling in the same direction on the same highway. How long will it take for the car to catch up to the truck, if both vehicles continue in the same direction on the highway?
R T = D
Truck 45 x = 45x
Car 60 x – 1 = 60(x – 1)
