Real-Life Math -- Solution
To estimate the total number of salmon which passed by your checkpoint
in the 1st week, use the figure you have to determine the number of salmon
per day, and then add the daily figures together.
Day 1: 886 salmon
per hour x 24 hours = 21,264 salmon per day
Day 2: 942 salmon per hour
x 24 hours = 22,608 salmon per day
Day 3: 922 salmon per hour x 24 hours
= 22,128 salmon per day
Day 4: 876 salmon per hour x 24 hours = 21,024
salmon per day
Day 5: 946 salmon per hour x 24 hours = 22,704 salmon per
day
Day 6: 849 salmon per hour x 24 hours = 20,376 salmon
per day
Day 7: 964 salmon per hour x 24 hours = 23,136 salmon per day
Total
= 153,240 salmon per week
To estimate the number of salmon for the
entire 23-day salmon run, use the weekly salmon total to calculate the average
number of salmon per day, then multiply it by the number of days in the run.
153,240
salmon per week / 7 days = 21,891 salmon per day
21,891 salmon
per day x 23 days = 503,493 salmon for the entire run
You estimate
0.5 million salmon will pass by your checkpoint during the 23-day salmon run.
