Final answer:
Lin took home a total of 16 boxes of vegetables from the market after subtracting the number of boxes sold from the total number she initially brought.
Step-by-step explanation:
To find out how many boxes of vegetables Lin took home, we start by calculating the number of boxes she sold and then subtracting that from the total number she brought to the market.
Lin sold 68 boxes of carrots and 71 boxes of potatoes. To find out the remaining boxes of each vegetable, we subtract the number sold from the total she brought:
Adding the remaining boxes of carrots and potatoes gives us the total number of boxes Lin took home:
7 boxes (carrots) + 9 boxes (potatoes) = 16 boxes
Therefore, Lin took home 16 boxes of vegetables from the market.
