You can put this solution on YOUR website!
y = 1000 for 0 <= x <= 3
y = 1000 + 400 * (x - 3) for x > 3

you're paying 1000 pesos for the rental if you keep it for 3 days or less.

you're paying 1000 + 400 per day over 3 if you keep it for more than 3 days.

y is the cost of the video rental
x is the number of days the video was rented for.
