nd P is the price of each session. Her marginal revenue is MR = 200-0.2Q Ms. Aura's operation has no fixed costs, but she incurs a cost of 150 per session (going to the client's house).
a. What is Ms. Aura's yearly profit?
b. Suppose Ms. Aura becomes famous after appearing on the Psychic Network. The new demand for her services is Q = 2500-5P. Her new marginal revenue is MR = 500-0.4Q. What is her profit now?

Answer:

a)

P 175

Q = 250

Profit6,250

b)

P 325

Q = 875

Profit 153,125

c)

Q = 1200

P = 260

Profit = 287,000

Explanation:

It maximize profit at MR = MC

MR = 200 - 0.2Q

MC = 150

150 = 200-0.2Q

Q = 50/0.2 = Q = 250

Price:

250 = 2000 - 10P

P = 1750/10 = 175

<u></u>

<u>Profit: revenue - cost</u>

$175 x 250 session - $150 per session = 6,250

<em>At new functions:</em>

150 = 500-0.4Q

Q = 350 / 0.4 = 875

Price:

875 = 2,500 - 5P

P = (2500-875)/5= 325

<u>Profit</u>

(325 - 150) * 875 = 153,125

<u>If cost changes:</u>

cost: 1000 + 20Q

marginal cost: 20

20 = 500 - 0.4Q

Q = 480 / 0.4 = 1,200

Price:

1,200 = 2500 - 5P

P = 1300/5 = 260

<u>Profit</u>

(260 - 20)Q - 1,000 = 287,000

"You need to have $15,000 in five years to pay off a home equity loan. You can invest in an account that pays 5.75 percent compo
Nana76 [90]

Answer:

I have to invest $11364.

Explanation:

The formula of Compound Interest is:

A = P(1+\frac{r}{n})^{nt}

where A = Amount

P = Principle

r = rate

n = Number of Compounding per year

t = total number of year

Here, A = 15000, r = 5.75% = 0.0575, n = 4(quarterly), and t = 5.

Putting all these values in above formula:

15000 = P(1+\frac{0.0575}{4})^{4\times5}

⇒ 15000 = P(\frac{4.0575}{4})^{20}

⇒ 15000 = P(1.014)^{20}

⇒ 15000 = P(1.320)}

⇒ P = 11364

Hence, I have to invest $11364 for 5 years.
