Answer:
Q1. Selena will have earned <em><u>$ 25.00</u></em> in interest by the end of the year.
Since interest paid is 5% in simple interest, we can calculate that by using the formula:


Q2. The balance in Suki's account at the end of two years will be <em><u>$866.2854.</u></em>
This means that she will have earned <em><u>$66.2854</u></em> in interest.
Since interest is compounded quarterly, Suki will receive interest for 8 periods. The formula for compound interest with more than one interest period per year is:

where
A is the amount at the end of the period
P is the principal
i is interest rate per annum
m is number of compounding periods in a year
n is number of years
Substituting the values in the formula above we get,



Now, we calculate the interest earned by doing \mathbf{CI = A -P}.

Q3. It will take <em><u>18 years</u></em> for the money to double to $100.
Since we need to use the rule of 72, we'll divide 72 by the interest rate to determine the number of years needed to double the investment's value.
So, the number of years is
.
Answer:
If the required reserve ratio is 0, that means that the money multiplier will be infinite. I guess the question is incomplete.
I looked for similar questions to fill in the blanks:
If you deposit $2,400 and the required reserve ratio is 0.4, then by how much does the money supply increase?
first we must determine the money multiplier = 1 / required reserve ratio = 1 / 0.4 = 2.5
to determine the total effect on the money supply we just multiply the deposit by the multiplier = $2,400 x 2.5 = $6,000 increase.
Answer:
C) 15 months
Explanation:
As per the law, a company with two or more shareholders must hold an Annual AGM every year. The AGM for a new company must be held within the first nines months after the financial year.
The AGM for an existing company must be held not later than six months after the end of a financial year. However, the law has set 15 months as the maximum gap of time allowed between two general meetings.
Answer: The probabilities of winning a contract are

Let the Probability of C winning the contract - P(C) be 'X'
Then,
Probability of B winning the contract - P(B) will be '7X' and
Probability of A winning the contract - P(A) will be 
Since the total of all the probabilities is 1,




So,
