Final answer:
The student must subtract the already sold 208 boxes from the 600-box goal to find 392 boxes remaining. Then divide that number by the 7 troop members to find that each member has to sell 56 boxes.
Step-by-step explanation:
The question asks us to determine how many boxes each troop member needs to sell for Doug's scout troop to reach their kettle corn sales goal of 600 boxes. They have already sold 208 boxes, so we first need to find out how many boxes are left to sell to reach the goal.
We subtract the number of boxes already sold from the goal: 600 boxes − 208 boxes = 392 boxes.
Next, we need to divide the remaining number of boxes by the number of troop members to find out how many boxes each member should sell:
392 boxes ÷ 7 troop members = 56 boxes per member.
Therefore, each member of Doug's scout troop must sell 56 boxes of kettle corn to reach their sales goal.
