## Bat And Ball Riddle

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

x + (\$1.00 + x) = \$1.10, so

\$0.05 + (\$1.00 + \$0.05) = \$1.10
