Question 1168104
<font face="Times New Roman" size="+2">

Multiply 25 times 20 and then add 200 to that product.  That is the amount he needs to have in his hand when he has sold all of them to have a $200 profit.  Multiply 15 times 18.  That is the amount he has now.  Subtract the amount he has now from the amount he needs to have and divide by 10 (the number he still has to sell after selling 15).  You should discover that he will need to find 10 extraordinarily naive customers in order to achieve his goal.
