B. 15
Explanation:
Let x be the number of chicken wings on the tray to start. According to the information given in the equation, after taking away 1/3 of the chicken wings, there were 9 left.
Therefore, we can set up the equation:
x - (1/3)x = 9
2/3x = 9
x = 9 / (2/3)
x = 13.5
Since the answer must be a whole number, the nearest whole number to 13.5 is 15. Therefore, there were 15 chicken wings on the tray to start.
4. Solve the equation above to find how many chicken wings were on the tray to start.
