Based on this year's costs, a company budgets P dollars for hiring N new employees next year. If the average cost of hiring each employee were to decrease 20% from this year's cost, then the greatest number of employees could hire next year using P dollars would be:  Pick one
A) Equal to N	B) 25% greater than N	C) 20% greater than N	D) 25% less than N	E) 20% less than N
Correct answer is (B).   This year, the price of an employee is price1=P/N.   If this price decreases by 20% it becomes Price2=P/N*0.8   Then with P dollars, you can hire P/Price2 employees i.e. P/(P/N*0.8) i.e. N/1.1 i.e. 1.25*N   Which is 25% greater than N.
