Population Growth Equation
M0 as our initial mass, d as our decay percent, and t as the units of time.
M(t) = M0(1 - d)t
pct =11% as a decimal is 0.11
We are given the following values:
M0 = 500, d = 0.11, and t = 6
Using our given values, our mass after decay is:
M(t) = 500(1 - 0.11)t
M(t) = 500(0.89)t
The problem asks for M(6)
M(6) = 500(0.89)6
M(6) = 500(0.496981290961)
M(6) = 248.4906454805
