## Solution 12223: Calculating Mark-Up, Gross Profit Margin, and Percent Change on the TI-5018.

### How do I calculate the Mark-Up, Gross Profit Margin, and Percent Change on the TI-5018?

The examples below will demonstrate using the Mark-Up key for calculations of mark-up, margin-up (or Gross Profit Margin), and percent change.

Example: Using [MU] for Mark-Up:

An item costing $355 needs to sell at a 16% profit. What is the selling price of the item, and how much profit will be made? Before beginning the calculation: Set the ROUND switch to 5/4. Set the GT switch to OFF. Set the DECIMAL switch to 2. Press [ON/C]. • Input the value 355, press the [x] key. • Input 16, then press [MU]. This calculates the selling price of the item, which is$411.80.

• Press the [MU] key again.

This calculates the amount of profit, $56.80. Example: Using the [MU] key for Margin-Up or Gross Profit Margin: Using a cost of$355 and a profit of 16% , calculate the selling price and profit as a margin calculation.

• Input the value 355, then press the [Division] key.
• Input 16, then press [MU].

This calculates the selling price, which is $422.62. • Press the [MU] key again. This calculates the profit,$67.62.

Example: Percent Change or Delta Percent Using the [MU] key:

What is the percent change between an original price of $140 and an increased price of$175?

• Input 175, [-], 140.
• Press the [MU] key.

This calculates the percent change, 25%.

• Press the [MU] key again.

This calculates the price difference, which is $35. What is the percent change between an original price of$175 and a discounted price of $140? • Input 140, [-], 175. • Press the [MU] key. The percent change is -20%. • Press the [MU] key again. The price difference (discounted) is$35.
