The value of a professional basketball player's autograph rose 10% in the last year. It is now worth $297.00. What was it worth a year ago?

OpenStudy (anonymous):

297 * .10=29.70 297 - 29.70=267.30 You can double check the answer by multiplying 29.70 by 10.

So, the price of the autograph one year ago was $267.30

hi I got this answer but they only give the answer choices: A. $270.00 B. $280.00 C. $260.00 D. $250.00

That means they are probably rounding the numbers. Let me try again.

Rounding numbers: 297 to 300 29.70 to 30 300 - 30=270
