For this chain-of-thought reasoning and answer, what was the question?
First, we find out how much in sales the stand makes each hour by multiplying the number of hot dogs sold by the sales price, finding that 2 * 10 = 20 dollars in sales each hour. Then we divide the sales goal for the day by the sales per hour, finding that the stand needs to be open for 200 / 20 = 10 hours to hit its sales goal.
 A: 10
Q: A hot dog stand sells 10 hot dogs every hour, each one selling for $2. How many hours does the stand need to run to make $200 in sales?
