Answer:

  $67 profit

Step-by-step explanation:

The average of three numbers is their sum, divided by 3. Let x represent the profit during the third month. Then the average monthly profit is ...

  (-29 + 115 + x)/3 = 51

  86 +x = 153 . . . . . multiply by 3, collect terms

  x = 67 . . . . . . . . . . subtract 86

Their profit the third month was $67.
