Question

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.

Answer 1

Riding a go-kart costs $10 on Saturday and Sunday and $5 on Monday through Friday.
=> From 10 dollars to 5 dollars
Let's solve how many percent did it decreases?
=> 5 / 10 = 0.5
=> 0.5 * 100% = 50%
50% is the percentage that decreases in the price.

Answer 2

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.
