We will solve for the rate being the annuity of 3 payment of 800
and the present value 2,138.41
C 800
time 3
PV 2,138.41
rate ?

For the second assignment:
we need to solve for time:
C 3,800
time n
rate 0.06
PV $31,897
We work out the formula:

Now we solve the right side and apply logarithmic properties

-n = -11.77128325
n = 11.77
It will take 12 years to obtain their target amount
