Question from Jack:

If a product cost me $\$10.00$ and I want a profit of 35% what is my sell price? How do I figure the sale price to make a 35% profit on the sale?

Hi Jack,

If you have a selling price of $\$P$ and your profit is 35% of $\$P$ then your cast is 65% of $\$P.$ Thus

\[0.65 \times \$P = \$10.00\]

Dividing both sides by $0.65$ gives

\[\$P = \frac{\$10.00}{0.65} = \$15.38\]
