You can put this solution on YOUR website!
let x equal the number of days for the rental.
let y equal the total cost.

your equations are:

y = 1000 for 0 <= x <= 3
y = 1000 + 400 * x for x > 3

if the number of days of the rental is less than or equal to 3 days, use the first equation.

if the number of days of the rental is more than 3 days, use the second equation.

            I came to bring a correct/(corrected) solution. 


let x equal the number of days for the rental.
let y equal the total cost.


your equations are:


y = 1000                for 0 <= x <= 3         (1)

y = 1000 + 400 * (x-3)  for x > 3               (2)


if the number of days of the rental is less than or equal to 3 days, use the first equation.


if the number of days of the rental is more than 3 days, use the second equation.


Look into my solution attentively and find the difference with the solution by @Theo.
