Cos 74°= Sin 16°
Sin 20°= Cos 70°
Sin A°=Cos (90°- A°)

These two claims about markup and margin are <u>equivalent</u> because they discuss differently the same issue.
<h3>What are markup and margin?</h3>
A markup is a profit percent added to the cost price to determine the selling price. Thus, markup relates the percentage of profit to the cost price.
The profit margin relates the percentage of profit to the selling price.
<h3>Data and Calculations:</h3>
Selling price = 100%
Profit margin = 25%
Cost price = 75% (100% - 25%)
Markup = 33% (25%/75% x 100)
Thus, these two claims about markup and margin are <u>equivalent</u>.
