Bat And Ball Riddle
If a baseball and a bat cost $1.10 together, and the bat costs $1.00 more than the ball, how much does the ball cost?
Hint: The answer isn't 10 cents.
Here's the solution:
Although $1.00 + $0.10 does equal $1.10, if you take $1.00 $0.10 you get $0.90, but the problem requires that the bat costs $1 more than the ball.
So, the ball must cost $0.05, and the bat must cost $1.05 since $1.05 + $0.05 = $1.10

Still not convinced? You can use algebra to solve the problem:
First, lets set up the equation:
x + ($1.00 + x) = $1.10
$1.00 + 2x = $1.10
2x = $1.10 $1.00
2x = $0.101
Finally, solve for x:
x = $0.05
Check your work:
x + ($1.00 + x) = $1.10, so
$0.05 + ($1.00 + $0.05) = $1.10 Did you answer this riddle correctly?
