Answer:
The answer is $86,167.57 (to 2 decimal places)
Explanation:
In this question, we are to calculate the present value of a certain amount that is compounded semiannually, and after 10 years, yields a future value of $200,000. To calculate this, we will use the formula for calculating present value as follows:
PV = FV ÷ 
where:
PV = present value = ???
FV = future value = $200,000
r = interest rate in decimal = 8.6% = 0.086
n = compounding period pr year = semiannually = 2
t = time of compounding in years = 10
Therefore,
PV = 200,000 ÷ 
PV = 200,000 ÷
= $86,167.57
For this case we have an equation of the form:

Where,
A: initial amount
b: growth rate
x: number of years
Substituting values we have:

By the time the earnings increase to 75000 we have:

From here, we clear x:

Answer:
A. An increase in the perceived profitability of Touchtech will likely cause the value of Edison's shares to rise.
B. Expectations of a recession that will reduce economy-wide corporate profits will likely cause the value of Edison's shares to decline

The price of the stock changes only because of the changes in the profitability of the firm. If the company is earning lower profits then the prices of the stock will fall and vice versa. So the option A is correct because increase in profitability increases the value of the shares.
So the main thing here is the profitability of the firm which is affected by the recession in the economy because during the recession period the profitability of the firm decreases and so the value of the stock decreases. So the option B is correct
