The mean investment return is:

The variance is:

The variance of the returns on this investment is A) 0.0618.
Answer:
The demand for Post Raisin Brand cereal is: ELASTIC
the demand for all types of breakfast cereals is: INELASTIC
Explanation:
To calculate the price elasticity of demand (PED) we can use the following formula:
PED = % change in quantity / % change in price
- If PED > 1, the demand is price elastic
- If PED = 1, the demand is price unitary
- If PED < 1, the demand is price inelastic
*The PED always results in a negative number, e.g. price deceases, quantity increases, but for practical reasons we convert the negative number into a positive (we use absolute values) when we are determining the elasticity.
Answer:
1. $1,250
2. $855.95
3. $3,333.33
4. $92.59
5. $46.32
6. $671.01
Explanation:
1.
$100 per year forever
Constant Cash flow every year forever is actually a perpetuity its present value is
PV of Perpetuity = Cash flow / rate of return
PV of $100 Perpetuity = $100 / 0.08 = $1,250
2.
$100 per year for 15 years
Constant Cash flow every year for specific time period is actually a Annuity its present value is
PV of annuity = P + P [ ( 1 - ( 1 + r )^-n ) / r ] = $100 + $100 [ ( 1 - ( 1 + 0.08 )^-15 ) / 0.08 ] = $855.95
3.
$100 per year grow at 5% forever
It is a growing perpetuity and its present value will be calculated as follow
Present value of growing perpetuity = Cash flow / Rate of return - growth rate
Present value of growing perpetuity = $100 / 0.08 - 0.05 = $3,333.33
4.
$100 once at the end of this year
Present value = P ( 1 + r)^-n = $100 ( 1 + 0.08 )^-1 = $92.59
5.
$100 once after 10 years
Present value = P ( 1 + r)^-n = $100 ( 1 + 0.08 )^-10 = $46.32
6.
$100 each year for 10 years @ 8%
PV of annuity = P + P [ ( 1 - ( 1 + r )^-n ) / r ] = $100 + $100 [ ( 1 - ( 1 + 0.08 )^-10 ) / 0.08 ] = $671.01
