Write two different quadratic equations to represent the function with a vertex of (3,-5).

Y=x^2+2x-15
x is squared

The answer is c because you turn 17.5% into a decimal which gives you .175 then you times that by $361.35 which gives you 63.23625 but then you round that which gives you 63.24. then you at 63.24 pulse 361.35 and you round it which gives you $425
