                            <U>Step by step</U>



(1)  At 9-Innings Baseball, the sale price of a baseball bat is  (1-0.2)*225 = 0.8*225 = 180 dollars.


(2)  At All-American Baseball, the same bat is on sale for 180 - 10 = 170 dollars after the 18% discount.


(3)  Let x be the original cost of the bat at All-American Baseball.

     Then, according to the problem, we have this relation

          (1-0.18)x = 170  dollars.

     or

          0.82x = 170.


     From this equation,  x =  {{{170/0.82}}} = 207.32  (rounded).


<U>ANSWER</U>.  The original cost of the bat at All-American Baseball is 207.32  dollars.
