Formally,
Let X be the price of the bat and
Let Y be the price of the ball.
X+Y=1.10 -— Eq 1
X-Y=1.00 -— Eq 2
Solve the equation simultaenously:
2X=2.10 (Step 2)
X= 1.05 (step 3)
From Eq 2:
1.05-Y= 1.00 (Step 4) (substitute 1.05 for X )
Y= 1.05-1.00 = .05 (Step 5)
Therefore:
X (Price of bat) = 1.05
Y (Price of ball) = .05
(Of course, in an actual TIMED test, you have to act fast and don’t have the luxury of doing the above ).
If obama had balls, Reggie Love would still be his manlove and would be massaging his $ 1.05 bat.
This isn't a logic problem, it's a 5th grade basic arithmetic problem and one of the easier ones to do.
