Answer:
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
