A. 11
B. 13
C. 7
D. 5
E. 2
Kudos for the right answer and explanation
The key here is to recognize that
the question does NOT state that x and y are integersGiven: -3 < y < x < 6B) 13
Let's first see if there is a way for x + y to equal 13, the greatest answer choice
Since we are told that x and y are each less than 6, there is no way for their sum to equal 13
Eliminate answer choice B
A) 11
Now let's try the second greatest answer choice, 11
Is there a way for x + y to equal 11?
You bet.
If x =5.9 and y = 5.1, then x + y = 11
Answer: A
