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

2. Solve for x: |2x – 8 | = 14

|2x – 8| = 14 2x – 8 = 14 or -(2x – 8) = 14 + 8 +8 -2x + 8 = 14 2x = 22 -8 -8 2 2 -2x = 6 x = 11 -2 -2 x = -3Answer: A

10. Solve: 0.6(p – 3) = 0.9p + 1.6 –

0.1pAnswer: 10[0.6(p – 3) = 0.9p + 1.6 – 0.1p] 6(p – 3) = 9p + 16 – 1p 6p – 18 = 8p + 16 -6p -6p -18 = 2p + 16 -16 -16 -34 = 2p 2 2 -17 = p

11. Alexa has $4.70 in nickels and quarters. In all, she has 30 coins in her wallet. Find the number of each kind of coin she has.

5(30 – x) + 25x = 470150 – 5x + 25x = 470 150 + 20x = 470 -150 -150 20x = 320 20 20 x =1616 Quarters 14 Nickels

13. Solve for x in the equation below. 8 + 2(3x + 9) = 6x – 10    Answer:

8 + 2(3x + 9) = 6x – 10 8 + 6x – 18 = 6x – 10 -10 + 6x = 6x – 10 Identity all real numbers

45x = 60(x – 1) 45x = 60x – 60 -60x -60x-15x = -60 -15 -15 x = 4The car will catch up to the truck in 3 hours

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)

15. Solve for n:

17. Solve for x.

(4x – 2) – 2x = 4 –

5(4x – 2) – 30x = 60 – 6x 20x – 10 – 30x = 60 – 6x -10x – 10 = 60 – 6x +10x +10x -10 = 60 + 4x -60 -60 -70 = 4x 4 4 x = 17.5
