Answer:
The correct answer is option D.
Explanation:
An interest rate is an amount charged by a lender on the use of assets. It is expressed as a percentage of the principal. The interest rate is the return on lending for a lender and the cost of borrowing for the borrower.
Interest is typically paid on a loan to compensate for the opportunity cost of lending money. A lender could invest the money instead of lending and get a higher return from it.
To compensate for not using the money for an alternative purpose or for temporarily making do without the money that was lent, the borrower pays a certain percentage of principal to the lender.
Answer: After 50 minutes the bell is at a depth of 2000 ft so we can find the average rate by
2000/50 =40 ft per minute.
We ignore the 400 ft in 12 minutes because that is included when we take out the average at 50 minutes and adding it in would be an error of doubly entry.

Simplest way to solve this problem is realizing that if 50% of all foreign students smoke, then that also means that 50% of all foreign students don't smoke (100% - 50% = 50%). So for every smoking foreign student you see, there's a non-smoking foreign student. So just double the number of smoking foreign students to get the total number foreign students. So
5% * 2 = 10%</span>
