Chapter 5, Problem 20PE
When you borrow money to buy a house, a car, or for some other purpose, you repay the loan by making periodic payments over a certain period of time. Of course, the lending company will charge interest on the loan. Every periodic payment consists of the interest on the loan and the payment toward the principal amount. To be specific, suppose that you borrow $1,000 at an interest rate of 7.2% per year and the payments are monthly. Suppose that your monthly payment is $25. Now, the interest is 7.2% per year and the payments are monthly, so the interest rate per month is 7.2/12 = 0.6%. The first month’s interest on $1,000 is 1000 × 0.006 = 6. Because the payment is $25 and the interest for the first month is $6, the payment toward the principal amount is 25 — 6 = 19. This means after making the first payment, the loan amount is 1,000 — 19 = 981. For the second payment, the interest is calculated on $981. So the interest for the second month is 981 × 0.006 = 5.886, that is, approximately $5.89. This implies that the payment toward the principal is 25 — 5.89 = 19.11 and the remaining balance after the second payment is 981 — 19.11 = 961.89. This process is repeated until the loan is paid.

A company has several employees, all with different names, who perform interviews with
job applicants (one applicant is interviewed by one employee). The job applicants also have
different names. The interviewer makes appointments for interviews with the applicants.
Each applicant may be interviewed at several occasions, possibly by different interviewers,
but in that case the interviews take place during different days.
The company has special interview rooms. Each interviewer uses the same room for all
interviews during a day. A room may, however, be used by different interviewers during a
day, as long as the interviews don't collide in time.
The reservation of interview appointments is to be computerized. The database devel-
oper has decided to use a single relation for all data, with the following schema:
Interviews(interviewer, applicant, day, time, room)
a) From the text, find functional dependencies in the relation.
b) Find the keys of the relation.
c) Show that the relation is…

- Fergusonball players are given a star rating based on the number of points that they score and the number of fouls that they commit. Specifically, they are awarded 5 stars for each point scored, and 3 stars are taken away for each foul committed. For every player, the number of points that they score is greater than the number of fouls that they commit. Your job is to determine how many players on a team have a star rating greater than 40. You also need to determine if the team is considered a gold team which means that all the players have a star rating greater than 40. Input Specification The first line of input consists of a positive integer N representing the total number of players on the team. This is followed by a pair of consecutive lines for each player. The first line in a pair is the number of points that the player scored. The second line in a pair is the number of fouls that the player committed. Both the number of points and the number of fouls, are non-negative integers.…arrow_forwardThe National Bank of Erehwon handles money and maintains bank accounts on behalf of clients.

Then, the average daily balance is: averageDailyBalance =netBalance x d1-payment x d2d1 If the interest rate per month is, say, 0.0152, then the interest on the unpaid balance is: Interest= averageDailyBalance * 0.0152 Write a program using c++ compiler that accepts as inputnetBalance, payment, d1,d2, and interest rate per month.
