Solution

3) Option D) is correct

log_b(x+3)* x = log_b54

         (x+3)*x = 54

         x^2 + 3x - 54 = 0   =========> x = 6

4) Option A) is correct

A = 22660*(1 + 0.13*2.4) = 29729.92

I = A – P = $ 7069.92

5) Option D) is correct

A = 900*(1 + 0.03/4)^(4*2) = $ 955.44

7) Option D) is correct

PMT = PV[(r/n) / [1 - (1 + (r/n))^(-nt)]]

PMT = 70000[(0.12/12) / [1 - (1 + (0.12/12))^(-12*15)]]
PMT = 70000[0.01 / (1 - 1.01^-180)]
PMT = 840.12
PMT = $840.12

8) Option A) is correct
