The answer is $18. Put the 38 in the place of b, b being the amount of times someone rides the bus. Hence, C=0.25(38) + 8.50. Then, multiply the multiplable numbers. You get 9.5. Add 9.5 and 8.50 to get 18.
Given:
Total students = 60
Student passed = 85%
To find:
The number of students who failed and then convert it in %.
Solution:
We have,
Number of passed student = 85% of Total students
= 
= 
So, number of passes students is 51.
Number of students who failed = Total students - Passes students
= 
= 
So, number of students who failed is 9.



Therefore, 15% students fail in the test.
