Answer :
Final answer:
To calculate the overall weight of 100 students, we multiply the average weight of the first 3 students by 3, and the average weight of the next 97 students by 97, and then sum those totals to get 16,216 pounds.
Explanation:
The question asks about calculating the overall weight of 100 students given the average weights of two separate student groups. First, we can find the total weight of the first group by multiplying the average weight of the first 3 students by 3, which equals 135 pounds times 3 students, giving us 405 pounds.
Next, we calculate the total weight of the second group by multiplying the average weight of the next 97 students by 97, which equals 163 pounds times 97 students, resulting in 15,811 pounds. Finally, we add these two totals together to find the overall weight of all 100 students.
To summarize the steps in calculation: Total weight of the first 3 students: 3 students * 135 pounds/student = 405 pounds. Total weight of the next 97 students: 97 students * 163 pounds/student = 15,811 pounds. Overall weight of all 100 students: 405 pounds + 15,811 pounds = 16,216 pounds. Therefore, the overall weight of all 100 students is 16,216 pounds.
