### Bat and ball Puzzler

Together a bat and a ball costs \$1.10

If the bat costs \$1.00 more than the ball, What are the costs for each bat and ball?

Ball \$__________?
Bat \$__________?
Total \$__1.10___

### Fast Thinking

At first glance or impulse, the simple subtraction 10 minus \$1.10.

The simple (incorrect) answer of 1.00 might indicate the cost of the ball is 10 cents.

But, wait, slow down a bit.

If the bat is one dollar more than the .10 cent ball, this means the bat alone would cost \$1.10.

This is incorrect because \$1.10 plus .10 exceeds the total, combined expenditure for bat and ball.

Ball             \$____.10______
Bat             \$___1.10_______
Total           \$___1.20___??

Correct solution is the ball costs

### Slow - Critical - Thinking

Since the bat costs one dollar MORE than the ball, the cost of the ball is .05, and at one dollar more, the bat is \$1.05.

Ball              \$_____.05_____
Bat              \$____1.05______
Grand Total  \$____1.10___
