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___
