Bill is saving for his son's college education. if the savings account earns 5% interest compounded monthly, and he wants to have $45,000 in 10 years, what must the principal be?

Total money that will be in the account in 10 years = 45000

Time period = 10 years

Rate of interest = 5% or 0.05

n = 12 (number o times the money is compounded)

Let the principal (p) be = x

Formula for compound interest =

Putting the values in the formula we get,

Hence, the principle amount should be approximately $27881.

(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

idk man good luck man
