Using a cosine function, where time is measured in hours past high

A merchant buys a television for $125 and sells it for a retail price of $200. What is the markup
beks73 [17]
The markup is the percent of the original price that it is increased by. To determine the percentage marked up, you will subtract the new price and the original price, and then divide that by the original price.

200-125=$75

75/200=0.375 or 37.5% markup.
