Question 24903
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?
{{{750/25 = 30}}}

Again if all but 10 were sold it means that there were originally 30+10 = 40jackets
