Bat and Ball
submitted by Alan Rench

A bat and ball cost $1.10.   The bat costs a dollar more than the ball.
How much does the ball cost?

No second chances on this problem and you must show your work.

Solution:

The ball cost five cents.

Let x = cost of the ball.
Then x + 1.00 = cost of the bat

So x + (x + 1.00) = 1.10
2x = .10
x = .05
