She should have to pay $380.25 in interest for the jet ski.
The x values decrease by 12 and the y increase by 4.
Answer: (x-12, y+4)
Simplified: x^3+5x^2-2x+1
in standard form: x^3+5x^2-2x+1
The best way to answer this would be making a graph

For 3 signs it costs 63.50 and he makes 45
For 4 signs it costs 68 and he makes 60
For 5 signs it costs 72.50 and he makes 75
