Answer:
21
Explanation:
Given that:
The utility function U(x, y) = 
The budget line income is:
105=4x +3y
The equation MRTS is:
where;
and:
∴
Using the equation MRTS:
4x = 12y
x = 12y/4
x = 3y
Replacing the value of x into the budget line income, we have:
105 = 4x + 3y
105 = 4(3y) + 3y
105 = 12y + 3y
105 = 15y
y = 105/15
y = 7
Then, from x = 3y
x = 3(7)
x = 21
Thus, she will consume 21 gapefruits
Answer:
When the price of good y increases by 10% it will result in the quantity demanded of x to increase by (0.6*10) =6%. The current quantity demanded of good x is 10 so a 6% increase will mean the quantity demanded of x will be (1.06*10)= 10.6
Explanation:
The cross elasticity of goods x and y is 0.6, which means that a one percent increase in price of good y will increase the demand for good x by 0.6%, this means that x and y are substitute goods, as when the price of y increases people tend to buy more of x.
When the price of good y increases by 10% it will result in the quantity demanded of x to increase by (0.6*10) =6%. The current quantity demanded of good x is 10 so a 6% increase will mean the quantity demanded of x will be (1.06*10)= 10.6
Answer:
The most sensible position is to understand that theory, while not practical in itself, can be immensely helpful when dealing with pratical matters.
This is because theory gives you a sound conceptual foundation that can be used to analyze the practical context, and approach it with the best possible practical solutions.
Without theory, managers have to rely too much on intuition, which can often fail.
Answer:
a. have performance attributes that are difficult to ascertain at the moment of purchase
Explanation:
In case of an experience good, it is difficult to make predictions regarding its price and quality.
The reputation of a seller and word of mouth are the important things that customers can use to make decisions regarding purchasing of the product.
Experience goods are those which have performance attributes that are difficult to ascertain at the moment of purchase
Answer:
To evaluate the choice, we have to calculate the present value of future cash flows and compare it with the cost. We use the following formula
present value = C × [ 
]
where
C = yearly payments = 75000
i = interest rate = 8%
n = no. of years = 15
put the given values in above equation, we get
Present value = 75000 ×8.559478688
= 641,961
Since the present value of cash flow 641,961 is less than the cost 750,000, I would not recommend it.
If Interest rate = 5%, then:
Do the same procedure as above but take i=5%
Present value = 75000 × 10.37965804
= 778,474
Since the present value of future cash flows 778,474 is greater than the cost 750,000, I would recommend it.
