To compute the selling price based upon cost: 1. Multiply the cost by the markup percent to get the dollar markup Add the dollar markup to the cost to get the selling price.

4. Key Terms / Items (continued)
To compute the selling price directly from the cost: 1. Add 100% to the markup percent Multiply this sum by the cost to get the selling price.
To compute the cost from the markup percent: 1. Add 100% to the markup percent Divide the selling price by this sum to get the cost.

5. Key Terms / Items (continued)
To compute the markup percent based on cost: 1. Subtract the cost from the selling price to get the dollar markup Divide the dollar markup by the cost to get the markup percent.
To compute the dollar markup AND cost from the markup percent: 1. Multiply the selling price by the markup percent to get the dollar markup Subtract the dollar markup from the selling price to get the cost.

6. Key Terms / Items (continued)
