Irene invested $27,000 in a twelve-year CD bearing 8.0% interest, but needed to withdraw $6,000 after three years. If the CD’s penalty for early withdrawal was eighteen months’ worth of interest on the amount withdrawn, when the CD reached maturity, how much less money did Irene earn total than if she had not made her early withdrawal? a. $3,600 b. $4,320 c. $720 d. $5,040 Please select the best answer from the choices provided A B C D

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
