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 increase 30% from this year's cost, then the greatest number of trees that the orchard grower could plant next year using P dollars would be
Select.
A) 23% less than N	B) 25% less than N	C) equal to N	D) 20% greater than N	E) 25% greater than
Correct answer is (A).   This year, the price of a tree is price1=P/N.   If this price increases by 30% it becomes price2=P/N*1.30   Then with P dollars, you can grow P/price2 tress i.e. P/(P/N*1.30) i.e. N/1.30 i.e. 77%
