Calculate values for the “unused portion of K, [1-(N/K)]” (round up to the second decimal) and for the population growth rate (ΔN/Δt) (round up to the nearest highest whole number). The values of N used here are estimated from the model using r_max = 0.15 and K = 7500 (you will look at the actual recorded data for N later in this lesson). Click here if you need help.
