Cecilia set a goal to raise $2,500.00 for her favorite charity this year. She has decided to participate in a walk-a-thon to help her reach her goal. She found 60 sponsers and each sponser has agreed to give her $0.65 for each mile that she walks in the walk-a-thon. Which of the following functions shows the remaining money that she needs to raise this year, G, as a function of the number of miles that she walks in the walk-a-thon, m?

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
