(a) Most obvious are the violations of Canons number 4 and 5. Unfaithfulness to the client and
deceptive acts are clearly present.

vary from the ethical (stating the truth and accepting the consequences) to unethical (continuing to

Lessons can be learned from the experience. A few of them are:

• Face ethical-dilemma situations honestly and make better decisions in real time.

Interest Rate and Rate of Return b b b b b




1.11 Extra amount received = 2865 - 25.80*100 = $285
b b b b b b b b




Rate of return = 285/2580 b b b b b




= 0.110 (11%) b




Total invested + fee 2865 + 50 = $2915 b b b b b b b b




b Amount required for 11% return = 2915*1.11 b b b b b b




= $3235.65 b




1.12 (a) Payment = 1,600,000(1.10)(1.10) = $1,936,000
b b b b b




(b) Interest = total amount paid – principal
b b b b b b b




= 1,936,000- 1,600,000 b b




= $336,000 b




1.13 i = [(5,184,000 – 4,800,000)/4,800,000]*100% = 8% per year
b b b b b b b b




1.14 Interest rate = interest paid/principal b b b b




= (312,000/2,600,000) b
