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? Let's answer step by step:
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. The answer: 10.
