Bill had $500 in a savings account at the beginning of the summer. He wants to have at least $200 in the account at the end of the summer. Bill withdraws $25 each week for food, clothes, and movie tickets. Define a variable, then write an inequality that represents Bill's situation.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
