Problem 1: Answer. Part 1 T= 60 months; R= 1.5%p.m; principle=\$4000 F.V = P.V*e^rt =\$4000*2.71828^1.5%*60 =\$4000*2.71828^.9 =\$4000*2.45960311116 =\$9838.4 Part 2 T= 60 months; R= 1.5%p.m; principle=? P.V= F.V/e^r*t P.V= \$5000/2.71828^.9 =\$5000/2.4596031116 =\$2032.84. part 3 assume amount to be invested monthly be X F.V=p.v*(1+i)^n \$5000=X*(1+1.5%)^60+X*(1+1.5%)^59+ ................ X*(1+1.5%)^1)+X \$5000=X(1+1.5%)^60+(1+1.5%)^59+ ........... (1+1.5%)^1) \$5000=X(2.44+2.40+2.37++2.33+2.30+2.27+2.24+ ......... 1.015) X=\$5000/(2.44+2.40+2.37++2.33+2.30+2.27+2.24+ ......... 1.015 Problem 2: Solution Rate per month = 6.99%/12 = 0.5825% Total number of payments in 4 years = 12*4 = 48

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
