Question 486893
he buys 12 computers for $15,000.
divide 15,000 by 12 and the computers cost him $1250 per computer.
$2150 - $1250 = $900 profit per computer.
that's the difference between the sale price and what it cost him.
$900 / $1250 = .72 * 100% = 72% profit on each computer.
a different way of looking at it is:
he bought 12 computers for $15,000
he sold 12 computers for $2150 apiece for a total sale price of $25,800.
his total profit was $25,800 - $15,000 = $10,800.
his percent profit was $10,900 / $15,000 = .72 * 100% = 72% profit.
