M: Hey, Linda, do you get that letter about the new options for food service next year?
W: Not yet. Are there a lot of changes?      
M: There sure are. Instead of paying one fee to cover all meals for the whole school year, we are now able to choose how many meals per week we want and can contract for just that amount, we can choose between seven, ten, fourteen or twenty-one meals per week.
W: That’s quite a complicated system.        
M: Yeah, but it will be much better for people who don’t eat three meals a day, seven days a week in the cafeteria, because they won’t have to pay for meals they don’t eat.
W: So what’s the deal for those who do eat at school all the time?
M: It’s better for them, too. Because the more meals you contract for, the cheaper each one is.
W: I see. It still sounds rather complicated.      
M: True, It takes me several hours to figure it out. I decide to go with the ten-meal plan.
W: Why is that?
M: I never eat breakfast and I often go away on weekends. So the ten-meal plan gives me lunch and dinner each weekday at a fairly low price. And I won’t be paying for meals I don’t usually eat.
W: And what about the weekend when you are on campus?        
M: Well, they allow you to buy single meals on Saturdays and Sundays. The price per meal is much higher in that way, but it will still be less money for me to pay single prices at weekends rather than sign up for the fourteen-meals-a-week plan.
W: I guess I will have to sit down and figure out my eating pattern, so I can get the best deal.
