A. a markup of 32%

B. a markup of 19%

C. a markdown of 49%

D. a markdown of 12%

## Markup:

In economics, a markup is difference between the sale price of a good and the cost of the good. Markup is usually expressed as a percentage of the cost.

We first compute the current price:

• price = cost *(1 + markup)
• price = 20 *(1 + 46%)
• price = 29.2

When there is a markup, the price increases. When there is a markdown, the price decreases. Thus, the price after the adjustments is:

• 29.2 *(1 + 32%)*(1 + 19%)*(1 - 49%)*(1 - 12%) = 20.59

That is, the final price is \$20.59.
