When you lose money on an investment, that's loss. When you make money on an investment, that's profit. When you express profit as a percent, that's return. Use the following formulae to calculate this next batch of problems.



Example: Dave buys a comic book for $2.50 when he's 7 years old. Ten years later, he sells it for $42.50. What's his profit & return?

Find Profit: Subtract Final Value - Original Value
$42.50 - $2.50	= $40.00 Profit
$40.00 / $2.50 x 100	= 1600% Return
