Answer:
80 years
Explanation:
Data provided in the question:
Simple interest rate charged = 1.25% = 0.0125
Now,
Let principal amount be '$x'
we know, Simple interest = Principal × Interest Rate × Time
Since the debt is doubled this means the interest is equal to the principal amount
Therefore,
$x = $x × 0.0125 × Time
or
1 = 0.0125 × Time
or
Time = 1 ÷ 0.0125
or
Time = 80 years
Answer:
Lerner index for Botox = 0.9
Explanation:
The Lerner index measures market power in an industry. The formula for calculating the Lerner index is: L = (P - MC) / P
Lerner index for Botox = ($15 - $1.50) / $15 = 0.9
0.9 in the Lerner index means that a company has a very large market power. Under this situation, this is quite logical since Allergen has a monopoly on Botox, at least until the patent expires.
The Lerner index varies between 0 and 1, with 0 being a situation of perfect competition and 1 a monopolistic situation.
Answer:
Explanation:
The journal entry is shown below:
Cash A/c Dr $2,200
To Service revenue $2,200
(Being cash is received)
Since the cash is received so we debited the cash account and credited the service revenue account as the service is completed which create an income for the business organization.
We do not write unearned service revenue as the amount is actually received from the customer
The effective interest rate on a discounted note is
.. 1/(1-r) = 1/0.9 ≈ 11.11%
_____
The amount and time have nothing to do with it for simple interest.
