The coach purchased b balls for d dollars. If each ball had cost $2 more, how many balls could the coach have purchased for $200?
--------------
The original purchase cost d/b dollars per ball
If each cost $2 more they each cost d/b+2
How many could be bought at this price for $200?
Ans: 200/[d/b + 2]
=200/[(d+2b)/2]
=400/[d+2b] is the number of balls that can be bought at the new price.
