Problem: if 5 < x < 9 and y = x + 3 , what is the greatest possible integer value of x + y ?
Rationale: "x + y = x + x + 3 = 2 x + 3 we need to maximize this value and it needs to be an integer . 2 x is an integer when the decimal of x is . 0 or . 5 the largest such value is 8.5 then x + y = 8.5 + 11.5 = 20 . the answer is b ."
