Answer: [tex]\\[/tex](a) Saving balance = $20,600
[tex]\\[/tex]Interest = $600
[tex]\\[/tex] (b) Total in Mutual fund = $26,503.34
[tex]\\[/tex] Interest earned = $3,903.34
[tex]\\[/tex](c) Money Earned from Savings Account= $11,330
[tex]\\[/tex] Money Earned from Stock Market:$12,100
[tex]\\[/tex] (2a) Monthly Payment = $7,503.93
[tex]\\[/tex]Total Amount Paid = $90,047.18
[tex]\\[/tex] (b) Monthly Payment =$6,753.53
[tex]\\[/tex] Total Amount Paid = $81,042.46
[tex]\\[/tex](c) Peer - peer lending and index fund
Step-by-step explanation:
[tex]\\[/tex]The Original money, which is the principal , in the savings account is $2,000
[tex]\\[/tex]Savings each year = $2,000
[tex]\\[/tex]Savings for 10 years = $2,000 x 10 = $20,000
[tex]\\[/tex]Annual Interest rate = 3%
[tex]\\[/tex]Interest for 10 years = PTR/100
[tex]\\[/tex]= 2000 x 10 x 3 / 100
[tex]\\[/tex] = 600
[tex]\\[/tex]Total savings after 10 years = saving + interest
[tex]\\[/tex]= $20,000 + $600
[tex]\\[/tex]= $20,600
[tex]\\[/tex]Therefore:
[tex]\\[/tex]Savings balance = $20,600
[tex]\\[/tex]Interest earned = $ 600
[tex]\\[/tex](b) The savings + the extra $2000 = $20,600 + $ 2,000
[tex]\\[/tex]= $22,600
[tex]\\[/tex]Interest rate = 8%
[tex]\\[/tex]Interest = 22,600 x 1 x 8 / 100
[tex]\\[/tex]= $1,808
[tex]\\[/tex]That means profit = $ 1,808
[tex]\\[/tex]Re – investing the profit, we will take the profit as the principal and then calculate the compounded interest for 10 years using the formula
[tex]\\[/tex]A = P[tex](1+r)^{t}[/tex]
[tex]\\[/tex] = 1,808 (1.08)10
[tex]\\[/tex] = $3,903.34
[tex]\\[/tex]Amount in the mutual fund at the end of ten years implies
[tex]\\[/tex]$22,600 + $3,903.34 = $26,503.34
[tex]\\[/tex]Total in Mutual fund = $26,503.34
[tex]\\[/tex]Interest earned = $3,903.34
[tex]\\[/tex](c) Since half of the $2,000 is left in savings, it means we have [tex]\\[/tex]$1,000 in savings
[tex]\\[/tex]Savings after 10 years = $1,000 + 10 x $1,000 = $ 11,000
[tex]\\[/tex]3% of savings = 0.03 x 11.000 = $330
[tex]\\[/tex]Total money in Savings = $11,000 + $330
[tex]\\[/tex] = $11,330
[tex]\\[/tex]Also for Stock
[tex]\\[/tex]Money in stock after 10 years = $1,000 + 10 x $1,000 = $11,000
[tex]\\[/tex]10% of stock = 0.1 x $11,000 = $1,100
[tex]\\[/tex]Total money in Stock = $11,000 + $1,100
[tex]\\[/tex] = $12,100
[tex]\\[/tex]Total money = money in savings + money in stock
[tex]\\[/tex]= $11,330 + $12,100
[tex]\\[/tex]= $23,430.00
[tex]\\[/tex](2) Amount given = $5,000
[tex]\\[/tex]Loan = $50,000
[tex]\\[/tex]Interest rate on loan = 4%
[tex]\\[/tex]Calculating the amount the loan will yield after 15 years using the formula
[tex]\\[/tex]A = P[tex](1+r)^{t}[/tex]
[tex]\\[/tex]A = 50,000 ( 1 + 0.04)15
[tex]\\[/tex]A = $90,047.18
[tex]\\[/tex]Therefore the compounded interest ( C.I) = $90,047.18 - $50,000
[tex]\\[/tex] = $40,047.18
[tex]\\[/tex](a) If you do not use the $5,000 , the monthly payment = $90,047.18 / 12
[tex]\\[/tex]= $7,503.93
[tex]\\[/tex]And the total payment = $90,047.18
[tex]\\[/tex](b) If , $5,00 is used as the initial payment then the remaining loan will be
[tex]\\[/tex] $50,000 - $5,000 = $45,000
[tex]\\[/tex]So , we will have to calculate the amount $45,000 will yield after 15 years using the same formula
[tex]\\[/tex]That is : A = 45,000 (1.04)15
[tex]\\[/tex] A =$ 81,042.46
[tex]\\[/tex]Therefore the C.I = $81,042.46 - $45,000
[tex]\\[/tex]= $36,042.46
[tex]\\[/tex]Monthly payment = $ 81,042.46/ 12
[tex]\\[/tex] = $6,753.53
[tex]\\[/tex]Total payment = $81,042.46
[tex]\\[/tex](c) Method of investing the money
[tex]\\[/tex](i) Peer to peer Lending. Giving helping hand one could earn [tex]\\[/tex]money as they pay back the loan with interest. If the interest is set to be 20%, for 15 years , 5000 will yield
[tex]\\[/tex]5000(1.2)15 = $77,035.10
[tex]\\[/tex](ii) Index fund : Index funds are a collection of stocks, so your investment is automatically diversified. Index fund like E-trade could be invested into. Using the stock calculator , it would yield $141,144
[tex]\\[/tex](d) I would rather invest the money in E- trade since I am sure it would bring a profit more than the amount of the loan will yield after 15 years , I will even have more money to hold at habd
