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.
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.
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.
