Answer: The marginal benefit curve is downward.
The marginal cost curve is upward
Explanation:
Unlike the marginal cost curve, whose slope is often upwards, the marginal profit curve is generally known by its downward slope.
The optimum allocation of resources to a given product will take place when these curves are used. MB = MC always.
Answer:
$100,000
Explanation:
In the case of joint life policy, the other person who is covered in the policy has the right to claim the amount after death of one person
In the given case, the husband has died after 8 years of purchasing the joint-life policy due to an automobile accident. So, the wife has the right to claim for the policy amount i.e $100,000. This claim is valid for the only first death
Answer:
$34,244.98
Explanation:
For computing the settlement worth in present value terms first we have to determine the future value which is shown below:
Value at year 4 = Annuity × [1 - 1 ÷ (1 + interest rate)^number of years] ÷ interest rate
= $7,275 × [1 - 1 ÷ (1 + 0.07)^7] ÷ 0.07
= $7,275 × [1 - 0.6227497419
] ÷ 0.07
= $7,275 × 5.3892894016
= $39207.08
Now the present value is
As we know that
Future value = Present value × (1 + interest rate)^number of years
$39,207.08 = Present value × (1 + 0.07)^2
So, the present value is
= $39,207.08 ÷ 1.1449
= $34,244.98
We simply applied the above formula so that the present value comes i.e today's value
Answer:
The value of the initial deposit = $1269
Explanation:
Given - Account balance of 1723.57 the interest rate of the account is 3.4% compounded daily.
To find - If the account was opened 9 years ago, what was the value of the initial deposit
Proof -
We know that,
If the interest rate is compounded n times per year at an annual rate r, the present value of a A dollars payable t years from now is:
Here,
A = 1723.57
r = 3.4% = 0.034
n = 365 (because it is compounded daily )
t = 9
So,
we get
= 1723.57(1.000093151)⁻³²⁸⁵
= 1723.57(0.736396351)
= 1269.23066 ≈ $1269
∴ we get
The value of the initial deposit = $1269
Answer:
Real interest rate= 0.06 = 6%
Explanation:
Giving the following information:
Nominal interest rate= 12%
Inflation rate= 6%
<u>The inflation rate provides the opposite effect on the interest rate. It decreases the purchasing power of an individual. </u>To calculate the real interest rate, we need to deduct the inflation rate.
Real interest rate= 0.12 - 0.06= 0.06
