Answer :
Final answer:
The average weight of the four children, calculated by summing their individual weights and dividing by the number of children, is 82 pounds.
Explanation:
To calculate the average weight of the four children, you add their weights together and then divide by the number of children. The weights are 78, 84, 91, and 75 pounds.
Firstly, you sum the weights:
78 + 84 + 91 + 75 = 328 pounds total.
Then, divide the total weight by the number of children, which is 4:
328 ÷ 4 = 82 pounds.
Therefore, the average weight of these four children is 82 pounds.
