correct choices are b and c.

step-by-step explanation:

plot all points and determine that the data   is best represented by a quadratic model (see attached diagram). thus, option a is false and option b is true.

the quadratic function that represents the situation is

when x=5, then

so option c is true.

according to the attached diagram at x=80, the value of y is positive, then option d is false.

as the price per unit increases, the profit increases by known quadratic function, thus option e is false.
