Advanced Mathematics II Homework 1 & 2 (2011) Homework 1 Sect11-1 Q22 A family paid $40‚000 cash for a house. Fifteen years later‚ they sold the house for $100‚000. If interest is compounded continuously‚ what annual nominal rate of interest did the original $40‚000 investment earn? Solution. Using the continuous compound interest formula we have 100000 = 40000e15r ln(2.5) = 15r r = 0.061 where we have put t = 15‚ P = 40000 and A = 100000. Thus‚ the annual nominal rate should be 6.1% of

If math was a part of nature‚ man would be born with math knowledge‚ but man is not‚ man had to think about a way to count and measure things
