A hair stylist charges $30 for a woman's haircut and $10 for a man's haircut. It takes 1 hour to cut a woman's hair and 1/2 hour to cut a man's hair. Based on the
customer needs, the stylist must schedule at least 6 woman's hair cuts per day and
no more than 5 man's hair cuts per day. The stylist works for up to 10 hours per day.
If x represents the number of woman's hair cuts and y represents the number of
man's hair cuts, which of the following are the correct constraints?
