a store that buys and sells used video games buys a game at a cost of $9 and sells it at a selling price of $12. find the markup. then find the percent markup.

a) markup = $3

b) markup as a percentage of cost is 33.3%

Step-by-step explanation:

Markup

... markup = selling price - cost

... = $12 - 9

... markup = $3

Markup as a Percentage of Cost

To find the percent markup, divide the markup by the reference value and multiply the ratio by 100%. The reference value for markup is usually cost price, but sometimes may be selling price.

... markup / cost × 100% = 3/9×100% = 33 1/3% ≈ 33.3%

When the markup is figured as a percentage of selling price, the result is usually called margin. Some folks are not very careful in distinguishing markup from margin.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3
