Answer:
So unit elastic at q = 5
inelastic above 5
and elastic below 5
Explanation:
The elasticity is determianted by the marginal revenue.
Our first goal is to find the marginal revenue function
p = 40 - 4q
total revenue(TR) = quantity times price
q x (40 - 4q) = -4q^2 +40q
marginal revenue TR(q)/d(q) = -8q + 40
Now, with this fuction the economic analisys states that a demand is unit elastic when marginal revenue is zero.
It will be inelastic below zero and elastic above zero
MR will be zero when q = 5
-8(5) + 40 = 0
As quantity increases the demand will be inelastic

Answer: a. 10%
b. -30%
Explanation:
a. What is the percentage change in the price of milk?
Old price = $5.00
New price = $5.50
Percentage change = ($5.50 - $5.00)/$5.00 × 100
= 0.50/5.00 × 100
= 1/10 × 100
= 10%
Percentage change on price = 10%
b. What is the percentage change in the quantity demanded for Boo Berry Cereal?
Old quantity = 1000
New quantity = 700
Percentage change = (700 - 1000)/1000 × 100
= -300/1000 × 100
= -30%
The percentage change in the quantity demanded for Boo Berry Cereal is -30%.
Answer: -$100
Explanation:
Value of forward contract = Selling price - Forward price on bond
Forward price = Present value of cashflows + Present value of bond
Periodic rate = 7%/ 2 = 3.5% per semi annum
= 8% / 2 = 4%
3.5% will be used to discount the payment 6 months from now as that is the 6 month rate. The rest will be 4%.
= (80 / (1 + 3.5%) ) + ( 80 / ( 1 + 4%)²) + (940 / ( 1 +4%)²)
= $1,020.342
= $1,020
Value of forward contract = 920 - 1,020
= -$100
Answer:
d. $(6,642)
Explanation:
The present value is the sum of after tax cash flows.
Present value can be calculated using a financial calculator
Cash flow in year 0 = $-81,000
Cash flow each year in year 1 to 3 = $27,000 + $2,900 = $29,900
I = 10%
Present value = $(6,642)
To find the PV using a financial calacutor:
1. Input the cash flow values by pressing the CF button. After inputting the value, press enter and the arrow facing a downward direction.
2. After inputting all the cash flows, press the NPV button, input the value for I, press enter and the arrow facing a downward direction.
3. Press compute
