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?
Thoughts? Step-by-step reasoning:
User
He has 20 / 2 = 10 black socks. So he has 20 + 10 = 30 black and red socks. So he has 30 * 2 = 60 white socks. So he has 60 + 30 = 90 total socks.
Thus, the answer is 90.
