Day and Night Kennel charges $20 per day plus a one-time food fee of $15 to board a pet. Bark Time Hotel charges $30 per day plus a one-time food fee of $5. Which system represents this real-world situation?

See below.

Step-by-step explanation:

Let x represent the number of days.

Since Day and Night Kennel charges a fee of $20 per day and only a one-time fee of $15:

Where y represents the total cost, 20x represents the cost for staying x days and 15 is the initial one-time fee.

For Bark Time Hotel, similarly:

Again, y represents the total cost, 30x represents the cost for staying x days, and 5 is the initial one-time fee.

Thus, the system of equations is:

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
