Answer:

$X=\$1.64*10^9$

Step-by-step explanation:

From the question we are told that:

Population size $P=918000$

Rate of Population increase $\frac{dP}{dt}=9700$

Average annual income $I= \$34,549$

Rate of annual income increase $\frac{dI}{dt}=\$1300$

Generally the equation for Total Income is mathematically given by

$X=P \frac{dI}{dt}+I \frac{dP}{dt}$

$X=918000*1400+(9200*30593)$

$X=\$1.64*10^9$
