Answer
Estimate: 700,000; Exact: 618,642
Work Step by Step
To estimate the total loss of life, we round each number to the nearest hundred-thousand: 110,070 rounds to 100,000. 250,152 rounds to 300,000. 94,120 rounds to 100,000. 164,300 rounds to 200,000. Then we add 100,000 + 300,000 + 100,000 + 200,000 = 700,000. To find the exact number of deaths, we add all of the actual numbers together: 110,070 + 250,152 + 94,120 + 164,300 = 618,642
