Question from Arron: I have the retail price of $45.50. This price reflects a gross profit margin of 47%. How do I calculate the original cost of the item? |
Hi Arron,
If the profit margin is $47\%$ then the profit is 47% of the price the retail customer pays for the item. Thus the profit margin is $47\%$ of $\$45.50.$ Hence you can calculate the profit margin by $0.47 \times \$45.50$ and then subtract this from $\$45.50$ to find the original cost.
