Compute the requested value. Choose the correct answer.

If the cost is $138.25 and the desired markup is 12.5%, then what is the price after markup?

It is $.

155.53

153.39

151.77

The answer is 155.53

The cost is $138.25. This is 100%.

The desired markup is 12.5%. Let x be the price after t he desired markup. x is 112.5% (100% + 12.5% = 112.5%).

Again:

$138.25 is 100%

x is 112.5%

Make the proportion:

$138.25 : 100% = x : 112.5%

x = $138.25 * 112.5% : 100%

x = $155.53
