R = 1% monthly
Time n = 84 months
Down payment = $10000
Monthly payment = $700
Price of the most expensive home = down payment + present value of the monthly payments
Price of the most expensive home = 10000 + 700*(1-1/1.01^84)/.01
Price of the most expensive home = $49653.92

Correct Answer:
iii. 11.95%, compounding monthly
Working note:
Effective rate when 12% compounding quarterly = (1+12%/4)^4 - 1 = 12.55%
Effective rate when 11.85% compounding daily = (1+ 11.85%/365)^365 - 1 = 12.58%
Effective rate when 11.95% compounding monthly = (1+11.95%/12)^12 – 1 = 12.63%
Effective rate when 11.82% compounding continuously = e^.1182 - 1= 2.7182^.1182 – 1 = 12.55%
So, the best rate is 11.95%, compounding monthly.
