Question 1134395
i would think the migration rate is 7% per year.
if you use the formula of f = p * (1 + r) ^ n, then:
r = -.07 and the formula becomes f = p * (1 - .07) ^ n
r is then equal to -.07 or a loss of 7% per year.
note that percent is 100 * rate and rate is percent / 100.
not sure if that comes into play hear.
i would think that the migration rate is 7% per year without any of those other complexities being brought in.
