Answer: b). falls from a positive amount to another positive amount
Explanation: Given that diet coke and diet pepsi give the consumer equal level of satisfaction. Diet coke and diet pepsi are substitutes, since, the consumer does not care about consuming diet pepsi and diet coke. For substitute goods the consumer will buy the cheapest of the two. When pdc (price of diet coke) rises but it remains less than pdp(price of diet pepsi) then the consumption of dc will decrease but it will still be above the consumption of dp. Since it is still relatively less expensive than diet pepsi. So the consumer will buy diet coke than diet pepsi, which means consumption of diet coke, dc falls from one positive amount to another positive amount.
Answer:
the amount of money that must be invested now is $21068.87
Explanation:
Given that:
Nominal interest = 10%
Annuity = 7000
n = 8 years
The Effective interest rate is calculated by using the formula:
Effective interest rate = 
Effective interest rate = 
Effective interest rate = 0.1045
Effective interest rate = 10.45 %
Thus ; the the amount of money that must be invested now is the present value with the annuity of $7, 000 per year for 12 years, starting eight years from now.

PV = 7000 × 6.666056912 × 0.4515171371
PV = $21068.87
Thus; the amount of money that must be invested now is $21068.87
