a storeowner orders 25 calculators that cost $36 each. The storeowner can sell each calculator for $51. The storeowner sold 22 calculators to customers. He had to return 3 calculators that were never sold and pay a $5 charge for each returned calculator. What is the storeowner's profit?
$207 is the answer, multiply 25 x 36 and 22 x 51 and 3 x 5, then subtract the products from the first two multiplications and then subtract 15 and you get your answer.
