Question

Mr. Smith prod TNT stocks and $30 per share and sold it at $45 per share what was his percent profit

Answer 1

The percentage of profit can be calculated by means of the following expression:

$\text{profit}=\frac{\text{sale}-\cos t}{\cos t}\times100$

Where the sale is the sale price and cost is the cost at which the article was bought. In this case, the cost is $30 and the sale price is $45. By replacing 30 for cost and 45 for sale into the above expression, we get:

$\text{profit}=\frac{45-30}{30}\times100=\frac{15}{30}\times100=50$

Then, the profit percent is 50% (0.5)
