Based on this year's costs, an orchard grower budgets P dollars for planing N new trees next year. If the average cost of planting each tree were to decrease 50% from this year's cost, then the greatest number of trees that the orchard grower could plant next year using P dollars would be:	Pick one
A) 100% less than N  B) 200% less than N  C) Equal to N  D) 100% greater than N  E) 200% greater than N
Correct answer is (D).   This year, the price of a tree is price1=P/N.   If this price decreases by 50% it becomes Price2=P/N*0.5   Then with P dollars, you can grow P/Price2 trees i.e. P/(P/N*0.5) i.e. N/0.5 i.e. 2*N   Which is 100% greater than N.
