Answer: There are 16 vans and 36 buses and Option 'c' is correct.
Step-by-step explanation:
Since we have given that
For high school A,
Number of vans = 5
Number of buses = 3
Number of students = 188
For high school B,
Number of vans = 10
Number of buses = 5
Number of students = 340
So, Let the number of students in van be 'x'
Let the number of students in bus be 'y'.
According to question, it becomes;
So, first we do:
2(5x+3y=188)
10x+6y=376----------------(3)
So, from (2) and (3), we get that
so, put the value of y = 36 in the eq(1), we get that
Hence, there are 16 vans and 36 buses and Option 'c' is correct.

Answer:
Extremely large and small numbers that have many zeros are long to write and take up a lot of room. So, by using scientific notation a number can be written shorter. For example, numbers such as 295,000,000,000 can be shortened to 2.95x. This is easier to write and understand. This is why the scientific notation is used over standard.
