Question 24903: please help me understand and find the answer to the following problem:
a store bought a $3000 shipment of ski jackets and offered them for sale after a markup of @25 each. all but ten were sold, and the store made a profit of $750. how many jackets were in the shipment?
thanks

You can put this solution on YOUR website!
Let the price of each jacket be $X
If each jacket was sold at a mark up of $25, then each jacket was sold at $X+$25
This new selling price caused a profit of $750
Which means that the extra $25 per jacket caused the profit.
Now how many jackets would need to be sold to make $750?
750%2F25+=+30
Again if all but 10 were sold it means that there were originally 30+10 = 40jackets
