The original text is poor English.
I fixed it in order for it makes sense.
Pay attention !
Step by step
(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 = = 207.32 (rounded).
ANSWER. The original cost of the bat at All-American Baseball is 207.32 dollars.
Solved.
