where t is the time measured in months. The population is suddenly reduced to
40% of its steady state size by myxamatosis. If the myxamatosis then has no further effeect, how large is the population 8 months later? How long will it take

your equation is much too ambiguous .
How are x and y defined?
Is the exponent of 10 equal to -7 or is is it 10^(-7y) ?
what about the (10^6-y)?
Is that (10^6) - y , the way you typed it, or is it
10^(6-y)
