Answer this question:Kennedy grew tomatoes from three plants she had in her backyard. The first tomato plant produced two dozen tomatoes. The second plant produced 5 more than half as many tomatoes as the first plant. And the third plant produced two more tomatoes than the second plant. How many tomatoes did the three plants produce?
