The amount left after n filtering steps

In solution during a filtering process is given by the equation P(x)=800(2)^-0.4n, where n is the number of filtering steps. Find the amounts left for n= 0 and n = 5. Round to the nearest whole number..

800, 3200
800, 200
1600, 200

Solution Summary

By evaluating the exponential function, the solution shows the amount of solvent left after n filtering steps.
