Answer:

maximum income is $900

Explanation:

given data

oil change = $20

per day = 40 customer

increase = $ 2

dailer customers = 2

owner charge = $ 2

to find out

income from the business

solution

we know current income is 40 × 20

current income = $800

we consider here price increase x and income as function y

so y = (20 +2x) × ( 40 - 2x)    ........1

y = −4x² + 40x + 800

take derivative and put dy/dx = 0 for maximum

dy/dx = -8x + 40

0 = -8x + 40

x=5

so here from 1

y = (20 +2x) × ( 40 - 2x)

y = (20 +2(5)) × ( 40 - 2(5))

y = 30 × 30

y = 900

so maximum income is $900

n an open economy, why is the supply curve for dollars in the foreign-currency exchange market vertical?
Zarrin [17]

In an open economy, the supply curve for dollars in the foreing-currency exhange market is vertical, because the supply does not depend on the exchange currency rate.

The supply of dollars in an open economy depends on the interest rate, which is determined by the difference between imports and exports (which is the same as the difference between purchases and sales of foreign capital).

Degger [83]

Answer:

1.10

Explanation:

The computation of portfolio's beta is shown below:-

= Stock A Beta × Invested in Stock A ÷ Total value + Stock B Beta × (Total value - Invested in Stock A) ÷ Invested in Stock A

= 0.75 × $47,500 ÷ $100,000 + 1.42 × ($100,000 - $47,500) ÷ $100,000

= 0.75 × $47,500 ÷ $100,000 + 1.42 × $52,500 ÷ $100,000

= 0.75 × 0.475 + 1.42 × 0.525

= 0.35625 + 0.7455

= 1.10175

or

= 1.10

Therefore for computing the portfolio beta we simply applied the above formula.
