James visits 20 houses to try and make a sale. He manages to sell something in every house. The next day he visits twice as many houses but only sold to 80% of houses. If he sold two things at each house in each of the two days, how many items did he sell?

How many houses did James visit on the second day? ** The second day he visited 20*2=<<20*2=40>>40 houses
How many houses did James sell things at on the second day? ** So he sold things at 40*.8=<<40*.8=32>>32 houses
How many houses did James sell things at in total? ** So in total he sold things at 20+32=<<20+32=52>>52 houses
How many things did James sell? ** That means he sold 52*2=<<52*2=104>>104 things
