Studdy Solution

STEP 1

Assumptions1. The number of domestic passengers is611,749. The number of international passengers is106,909

STEP 2

We need to find the total number of passengers. We can do this by adding the number of domestic passengers and the number of international passengers.
Totalpassengers=Domesticpassengers+InternationalpassengersTotal\, passengers = Domestic\, passengers + International\, passengers

STEP 3

Now, plug in the given values for the number of domestic passengers and the number of international passengers to calculate the total number of passengers.
Totalpassengers=611,749+106,909Total\, passengers =611,749 +106,909

STEP 4

Calculate the total number of passengers.
Totalpassengers=611,749+106,909=718,658Total\, passengers =611,749 +106,909 =718,658In January,718,658 passengers arrived or departed at Terminal4.

STEP 5

To estimate the total number of passengers, we round the numbers to the nearest hundred thousand.Estimateddomesticpassengers=600,000Estimated\, domestic\, passengers =600,000Estimatedinternationalpassengers=100,000Estimated\, international\, passengers =100,000

STEP 6

Add the estimated numbers of passengers.
Estimatedtotalpassengers=Estimateddomesticpassengers+EstimatedinternationalpassengersEstimated\, total\, passengers = Estimated\, domestic\, passengers + Estimated\, international\, passengers

STEP 7

Plug in the values for the estimated number of domestic passengers and the estimated number of international passengers to calculate the estimated total number of passengers.
Estimatedtotalpassengers=600,000+100,000Estimated\, total\, passengers =600,000 +100,000

STEP 8

Calculate the estimated total number of passengers.
Estimatedtotalpassengers=600,000+100,000=700,000Estimated\, total\, passengers =600,000 +100,000 =700,000

STEP 9

Now, compare the estimated total number of passengers to the actual total number of passengers. The actual total is reasonably close to the estimated total, so the answer is reasonable.
In January,718,658 passengers arrived or departed at Terminal4. This is reasonably close to the estimated total of700,000 passengers.
