# When comparing prices for activities at a local recreation center, you notice that the center charges different prices on different days of the week. For example, riding a go-kart costs \$10 on Saturday and Sunday and \$5 on Monday through Friday. Is the cost a function of the activity type? Explain why or why not.

1. No, it is a function of day of the week.

Of course it might be indirectly if different activities are scheduled on weekends. Perhaps they include a jump or explosive crashes on weekends :)

3. The activity type would be the input and the cost would be the output. Because there are two different costs for the same activity, this would not be a function.
