Answer:

The population of the students at the University after 5 years is <u>442</u>.

Step-by-step explanation:

Given:

Current population of students is, $P_o=400$

Growth rate is, $r=0.02$

Time after which population is needed is, $t=5\ years$

Let 'P' be the population after 't' years.

Population growth is an exponential growth and the equation to determine the population after 't' years is given as:

$P=P_oe^{rt}$

Now, plug in 400 for $P_o$ , 0.02 for 'r', 5 for 't' and solve for 'P'. This gives,

$P=(400)e^{0.02\times 5}\\\\P=400\times e^{0.1}\\\\P=400\times 1.1052\\\\P=442$

Therefore, the population of the students at the University after 5 years is 442.
