One factor of the polynomial 3x3 + 20x2 − 21x + 88 is (x + 8). What is the other factor of the polynomial? (Note: Use long division.)

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)

$25 becasue a 10 increase would make it from 80 to 50
