Answer:
time = 318.77
It will be after 318 months
Step-by-step explanation:
We are asked to find the time of an annuity of 1,000 monthly payment
which present value is 180,000

C = 1000
rate = 0.004
time ??
PV = 180,000

We clear out the dividend:

Then we clear the power up, notice it is negative, so we have to multiply by (-1)


We now use logarithmics to solve for time

time = 319
