 Question 330729: How long would it take an investment of \$12,225 at 3 3/4% interest compounded quarterly to triple?Answer by stanbon(57967)   (Show Source): You can put this solution on YOUR website! How long would it take an investment of \$12,225 at 3 3/4% interest compounded quarterly to triple? ----- A(t)=Ao(1+(r/n))^(nt) ------ 3(12225)= 12225(1+(0.0375/4))^(4t) (1+0.0094)^(4t) = 3 Take the log of both sides and solve for "t": (4t) = log(3)/log(1.0094) --- 4t = 117.4221 --- t = 29.35 Rounding up you get: t = 30 years ===================================== Cheers, Stan H. ===========
