At the airport 42% of the people are there for international travel 51% of the people are there for domestic travel and the rest are airport staff of there are 7500 people at the airport how many staff members are there

525

Step-by-step explanation:

Given

42% are there for international travel and

51% are there for domestic travel

The rest are airport staff.

Add the % of those who are there for international travel and domestic travel. Then subtract the result from 100% to get the % of those who are airport staff.

That's

42% + 51% = 93%

% of airport staff = 100% - 93% = 7%

If there are 7500 people, airport staff will be % of airport staff divided by 100% and then the result multiplied by the number of people

That's

7% / 100% x 7500

0.07 x 7500

525

There are 525 staff members

there were 525 staff members at the airport.
