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 =15% as a decimal is 0.15
We are given the following values:
M0 = 100, d = 0.15, and t = 10
Using our given values, our mass after decay is:
M(t) = 100(1 - 0.15)t
M(t) = 100(0.85)t
The problem asks for M(10)
M(10) = 100(0.85)10
M(10) = 100(0.19687440434072)
M(10) = 19.687440434072
Round to nearest tenth:
Rounded to the nearest tenth, our mass is 19.7
What is the Answer?
Rounded to the nearest tenth, our mass is 19.7
