<h3>What is multiplication?</h3>
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
The markup percentage can be found by multiplying the ratio of the profit earned to the cost price by 100%.
Given that the cost price of the cookies is $4, while the selling price of the cookies is $12. Therefore, the marked-up percentage is,
Markup percentage = ($12-$4)/ $4 × 100%
= 8/4 × 100%
= 2 × 100%
= 200%
Hence, the marked-up percentage is 200%.
