<human>:  James has 20 pairs of red socks and half as many black socks. He has twice as many white socks as red and black combined. How many total socks does he have combined?
<bot>: How many black socks does James have? ** He has 20/2=<<20/2=10>>10 black socks
How many black and red socks does James have? ** So he has 20+10=<<20+10=30>>30 black and red socks
How many white socks does James have? ** So he has 30*2=<<30*2=60>>60 white socks
How many total socks does James have? ** So he has 60+30=<<60+30=90>>90 total socks
