<human>:  James has 3 fish tanks. 1 of the tanks has 20 fish in it and the other two have twice as many fish each as the first. How many total fish do they have?
<bot>: How many fish are in the second and third tanks? ** The second and third tank each have 20*2=<<20*2=40>>40 fish
How many fish are in total? ** So in total there are 20+40*2=<<20+40*2=100>>100 fish
#### 100
