Question

Last year, 800 students attended the career fair at West High School. This year, the number of students who attended the career fair increased by 5%. How many students attended the career fair at West High School this year?

804
805
840
1,200

The correct answer is: 840

HINT: Find the increased number of students who attended the career fair this year and add it with the total.
Complete step by step solution:
Number of students who attended the career fair last year at West High School = 800
Percentage increase of students who attended this year compared to last year = 5%
Increase in number of students compared to last year = 5% of 800
This can be calculated by, 800 × $5 over 100$ = 40
So increase in number of students this year = 40
Hence, total number of students who attended the career fair this year = 800 + 40 = 840
Hence option C is the correct answer.
