5 pears and 2 apples cost $16. 3 pears and 3 apples cost $15. How much does one apple cost? Choose the correct choice from the following.
A) 3.5
B) 3.25
C) 3
D) 2.5
E) 2
Let cost of 1 pear = x, let cost of 1 apple = y   5x + 2y = 16   y = (16 - 5x)/2   Again,   3x + 3y = 15   3x + 3((16 - 5x)/2) = 15   3x + 24 - 7.5x = 15   3x + 24 = 15 + 7.5x   9 = 4.5x   x = 2   Now plug this value into one of the initial equations:   5x + 2y = 16   5(2) + 2y = 16   10 + 2y = 16   2y = 6   y = 3   Answer: 3   ANSWER:3
