Answer and Explanation:
Relationship between price and demand:
D = (2400 - p)/(0.100)
p = 2400 - 0.100*D
then:
Total revenue = p*D
= 2400*D - 0.100*D^2
for a maximum revenue:
dR/dD = 0
2400 - 0.100*2D = 0
D = 12000
this is considered a demand

Answer: B) a trainee's performance declines after training
Explanation: Negative transfer occurs when previous learning hinders further learning. It is best defined as the interference of previous knowledge with new ones, wherein the new set of knowledge could hurt the performance of a new often related knowledge. A typical example could be changing from a right-handed to a left-handed wheel drive or from a manual to an automatic transmission. Negative transfer usually is problematic during the early stages of learning a new task but with experience, learners can correct the effects of negative transfer.

Answer:
Reinvestment risk
Explanation:
The mortgage banker would be most concerned about reinvestment risk, among other risks. Reinvestment risk relates to the inability to earn an original interest rate on an investment from periodic cash flows from the investment, thus limiting the overall rate of return on the investment.
In the question, since market mortgage rate has declined to 7.5%, the mortgage bank would have to reinvest the amount repaid from the original borrower at the new market rate, which is 1% lower than the ruling rate when the original borrower took the loan.
The problem would be compounded if the cost of funding to the mortgage bank was, for instance 8%. If that was the case, on the original loan, the mortgage bank was earning a (8.5% less 8% cost of funding =) 0.5% on the loan. However, due to the decline in market rates, the mortgage bank would have a cost of 8% compare to a market rate of 7.5% it would earn, thus resulting in a negative return of 0.5%.
