each of the following engineering economic problems, circle the most appropriato answer to each problem. This part is worth 40 pts. 1. A principal sum p is invested at a nominal interest rate r, compounded m times a year, for n years. The accumulated amount at the end of this period will be (a) P(1+r/m) (b) P(1+r/m) (c) 'P(1+r/m)/ (d) P(1+r/m)/ (e) None of these 2. In the formula P = F(1+i), the factor (1+i) is called the (a) Sinking fund factor (b) Single payment present worth factor (c) Single payment compound amount factor (d) Capital recovery factor Uniform series present worth factor 3. A fund established to produce a desired amount at the end of a given period by means of a series of payments throughout the period is called a sinking fund, and it is represented by the formula (a) A = F[1/(1+i)" -1] (b) A = F[(1+1)"/1] (c) A = P(1+i)- (d) A = P[{(1+i)" - 1}/i(1+i)"] (e) A = F[1/(1+1)")
