Answer by Theo(13342)   (Show Source): 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.
