80 times .30= .20x +.60(80-x)
24=.20x+48-.60x
Subtract 48 from both sides
-24=-.40x
Divide both sides by-.40
X= 60
60 liters of 20%

General pharmacy’s stock has a beta of 1.8 and an expected return of 14%, and sicoras corp.’s stock has a beta of 1.5 and an exp
Shalnov [3]
Given:
<span>General pharmacy’s stock has a beta of 1.8 and an expected return of 14%,
Sicoras corp.’s stock has a beta of 1.5 and an expected return of 16.2%.

Let Rf stand for risk free rate.
Let Rm stand for expected market return.

General Pharmacy: 14% = Rf + 1.8(Rm-Rf)
Sicoras Corp.: 16.2% = Rf + 1.5(Rm-Rf)

0.14 = Rf + 1.8Rm - 1.8Rf
0.14 = Rf - 1.8Rf + 1.8Rm
0.14 = -0.8Rf + 1.8Rm
0.14 + 0.8Rf = 1.8Rm

Rm = 0.14/1.8 + 0.8Rf/1.8
Rm = 0.078 + 0.444Rf

</span><span>0.162 = Rf + 1.5(Rm-Rf)
</span>0.162 = Rf + 1.5[(0.078+0.444Rf) - Rf]
0.162 = Rf + 0.117 + 0.666Rf - 1.5Rf
0.162 - 0.117 = Rf + 0.666Rf - 1.5Rf
0.045 = 0.166Rf
0.045/0.166 = Rf
0.271 = Rf

<span>Rm = 0.078 + 0.444Rf
</span>Rm = 0.078 + 0.444(0.271)
Rm = 0.078 + 0.120
Rm = 0.198

Rf = 27.1% ; Rm = 19.8%

The risk free rate is 27.1% and the expected market return is 19.8%.

To check, simply substitute the value of Rf and Rm in the above equation.

Suppose housing prices and stock prices decline significantly and cause autonomous consumption spending to decrease by $200 bill
kirill [66]

Answer: The change will be $400 billion.

Explanation: The marginal propensity to consume (MPC) is used to explain that increase in consumption is as a result of increase in income.

To calculate how much the equilibrium real GDP will change:

STEP1: CALCULATE THE MULTIPLIERS

multipliers = 1 ÷ (1 - MPC)

Where MPC = 0.

Therefore;

Multipliers = 1 ÷ (1 - 0.5) = 1 ÷ 0.5

Multipliers = 2

STEP 2: CALCULATE HOW MUCH THE EQUILIBRIUM REAL GDP WILL CHANGE;

Multipliers × change in consumption spending

2 × $200 billion = $400 billion

Equilibrium real GDP will change with $400 billion

Mayra offers to sell her home to Hanna for "about $100,000 plus closing costs" and has no other comments, provisions, or discuss
Ivanshal [37]

Answer:

The most probable result is that the court will declare the contract invalid and non-binding because the purchase price and important terms regarding the consideration involve are too vague and indefinite.

In order for a contract to be considered valid and binding, consideration must exist and the more precise the terms, the better. Consideration is something of value that both parties exchange. In this case it is a house vs. money, but the price is not specified.
