The "MU" key on a calculator stands for Markup. It's a function used to calculate the selling price of an item when you know the cost and the desired profit margin (markup percentage).
How Markup Works on a Calculator
The markup function helps you quickly determine the final selling price by automatically adding the profit to the original cost.
Example:
Let's say you bought an item for $120 and want to make a 25% profit margin on the sale. Using the "MU" key, you can find the selling price as follows:
- Enter the cost:
120 - Press the
MUkey. - Enter the desired profit percentage:
25 - Press the
%key.
The calculator will display the selling price, which is $160 in this example. It also implicitly calculates the profit, which is $40.
Calculation Breakdown:
- Cost: $120
- Markup Percentage: 25%
- Profit: $120 * 0.25 = $30
- Selling Price: $120 + $30 = $160
Therefore, the MU function allows for quick calculation of the selling price based on the cost and desired markup.
