Answer 1

Answer: (6) $172.50    (7) $74.80   (8) $106.65   (9) $141.20

              (10) $119.00    (11) 12.5% markup     (12) 15% markdown

Step-by-step explanation:

Use the following formula (+ for markup and - for markdown/discount)

Base Price ± (Base Price × markup/markdown) = Adjusted Price

6. Markup so add (+)

150 + (150 × 0.15) = x

150 +      22.5       = x

             172.50    = x

7. Markdown so subtract (-)

85 - (85 × 0.12) = x

85 -      10.2      = x

             74.80  = x

8. Discount so subtract (-)

135 - (135 × 0.21) = x

135 -       28.35    = x

              106.65  = x

9. Markup so add (+)

x + (x × 0.25) = 176.50

x  +    0.25x   = 176.50

        1.25x     = 176.50

               x     = 141.20

10. Markdown so subtract (-)

x - (x × 0.15) = 101.15

x -    0.15x    = 101.15

         0.85x = 101.15

                 x = 119.00

11. The adjusted price is more than the base price so add (+)

278 + (278 × x) = 312.75

278 +      278x  = 312.75

              278x  = 34.75

                    x  = 0.125

                    x  =  12.5% markup

12. The adjusted price is less than the base price so subtract (-)

157 - (157 × x) = 133.45

157 -    157x    = 133.45

         -157x     = -23.55

                x     = 0.15

                x     = 15% markdown
