Respuesta :
The total Amount Spent by the volleyball team spend on shirts from the given piecewise function is; $260
How to work with Piecewise Function?
From the given piecewise function, we see that;
y = {13n, 0 < n ≤ 20
y = {11n, 20 < n ≤ 50
y = {9n, n > 50
We are told that the volleyball team purchased 20 shirts.
From the first piecewise function, we can deduce that;
Amount Spent = 13n = 13 * 20
Amount Spent = $260
