A Correct answer
Explanation

Statement (1) gives total revenue (1.5 million) and the price per bike (12,500). Dividing 1,500,000 by 12,500 gives 120 bikes. Statement (2) provides only a percentage of revenue donated, which is insufficient to find the number of bikes.

AI explanation

To find the number of bikes sold, we divide the total revenue by the average price per bike. Statement (1) gives the total revenue as \$1.5 million, or \$1,500,000. Dividing this by the average price of $12,500 results in 120 bikes sold, making statement (1) alone sufficient. Statement (2) only provides the donation percentage and gives no revenue figures, so it cannot find the number of bikes. Therefore, statement (1) alone is sufficient, but statement (2) alone is not.
