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?
Thoughts? Step-by-step reasoning:
User
The second day he visited 20 * 2 = 40 houses. So he sold things at 40 * .8 = 32 houses. So in total he sold things at 20 + 32 = 52 houses. That means he sold 52 * 2 = 104 things.
Thus, the answer is 104.
