The population of the world xx years from 2010 is predicted to be

6,9e0,00743x\color{#4257b2} 6,9e^{0,00743x}

billion people. Let us predict the world population in 2030. First, we calculate

x=20302010=20.x=2030-2010=20.

Now we use the given formula and get

6,9e0,0074320=6,9e0,1486=6,91,160209=8,00544.\begin{align*} 6,9e^{0,00743 \cdot 20} &=6,9e^{0,1486} \\ &=6,9 \cdot 1,160209 \\ &=\color{#c34632} 8,00544. \end{align*}

Therefore, the world population in 2030 will be 8,00544billionpeople\color{#c34632}8,00544billion people , or we can say that the world population will be slightly bigger than $\text{\color{#c34632} 88 billion people.}$
