Answer:

$P=750 e^{0.00963t}$

The population size would be 753,190 after 30 days

Explanation:

Since, the population growth function is,

$P = P_0 e^{rt}$

According to the question,

if t = 0, P = 750,

$\implies 750 = P_0 e^0\implies P_0 = 750$

Also, if t = 72, P = 1500,

$\implies 1500 = P_0 e^{72r}\implies 1500 = 750 e^{72r}\implies 2 = e^{72r}\implies \ln 2 = 72r\implies r = \frac{\ln 2}{72}\approx 0.00963$

Hence, the required function would be,

$P=750 e^{0.00963t}$

If t = 720 hours ( 30 days = 720 hours ),

Then, the population after 30 days would be,

$P=750 e^{0.00963\times 720}=750 e^{6.912}=753190.30695\approx 753190$
