We know that today 20 people have the flu and that this numbers double each day. This means that the second day we will have:

$2\cdot20$

the third day we will have:

$2\cdot(2\cdot20)$

The fourth day we will have:

$2\cdot(2\cdot(2\cdot20))$

And so on. From this we can conclude that in the t day we will have:

$f(t)=20\cdot2^t$

Now, in the 10th day we will have:

$f(10)=20\cdot2^(10)=20480$

20480 people with the flu.
