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?
How much in sales does the stand make each hour? ** 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=<<2*10=20>>20 dollars in sales each hour.
How many hours does the stand need to run to make $200 in sales? ** 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= <<200/20=10>>10 hours to hit its sales goal.
