3. Mrs. Fernandez’s Cookie Factory makes different –sized packages of cookies that contain a combination of chocolate chip and peanut butter cookies. Mrs. Fernandez places at least three of each type of cookie in each of the combination packages. The largest package, the “Baker’s Dozen”, contains thirteen cookies. It costs Mrs. Fernandez $0.19 to make a chocolate chip cookie and $0.13 to make a peanut butter cookie. She sells them for $0.44 and $0.39 respectively. Let c represent the number of chocolate chip cookies and let p represent the number of peanut butter cookies. What is the equation that represents the objective quantity function to find the profit?

1. C.
2. D.

4. Dolores arrives at school late because her car broke down, and therefore, has only 45 minutes to complete a history exam. The exam has 2 open-ended questions and 30 multiple-choice questions. Each correct open-ended question is worth 20 points, and each multiple-choice question is worth 2 points. She knows that it usually takes her 15 minutes to answer an open-ended question and only one minute to answer a multiple-choice question. Assume that for each question Dolores answers, she receives full credit. Let x represent the number of open-ended questions answered, and let y represent the number of multiple-choice questions answered. All of the following represent inequalities for this problem EXCEPT:

1. C.
2. D.

5. Is (x + 1) a factor of (x3 + 4x2 + 2x - 1)?

A)no because there is no remainder

B)no because there is a remainder

C)yes because 1 is a root

D)yes because there is no remainder

6. F(x) = x + 2 and G(x) = x4 ; find F(G(2))

7. g(x) = 4x and f(x) = 4x – 1 find 6g(x) – f(x)

8. f(x) = 15(x2 + 8x + 15) and g(x) = 5(x + 3) ; find
