## Solution 11212: Calculating Cost-Sell-Margin (CST-SEL-MAR) and Markup (MU) Using the BA-35 Solar Financial Calculator.

### How do I calculate cost-sell-margin (CST-SEL-MAR) and markup (MU) using my BA-35 Solar?

Example 1: The selling price (SEL) of an item is $125.00. The gross profit margin (MAR) is 20%. Find the orginal cost (CST). 1) Press [2nd] [CMR] to clear the memory registers. Use the [MODE] key to enter profit margin mode (no display indicator). 2) Enter 125 and press the [SEL] key. 3) Enter 20 and press the [MAR] key. 4) Press [CPT] [CST] to compute the cost which should be$100.00.

Example 2: The cost (CST) to manufacture an item is $175.00. The item was sold (SEL) for$210.00. What is the markup (MU)?

1) Press [2nd] [CMR] to clear the memory registers. Use the [MODE] key to enter profit margin mode (no display indicator).
2) Enter 175 and press the [CST] key.
3) Enter 210 and press the [SEL] key.
4) Press [CPT] [2nd] [MU] to compute the markup (MU) which should be 20. Since markup (MU) is normally a percentage, the solution is 20%.
