Question 1 As a fundraiser, the band is selling cookies. The cost to make each cookie can be written as c(x) = 0. 25 x + 0. 5 and the functions that represents the amount they sell the cookie for can be written as s(x) = 2 x. What function represents the profit, P(x), for each function? A) B) C) D) P(x) = 0. 5 x + 1 P(x) = 0. 5 x 2 + x P(x) = 2. 25 x + 0. 5 P(x) = 1. 75 x - 0. 5
Question 2 Which explicit rule describes the sequence below? 1, 7, 13, 19, 25… a. an = 6 n +1 b. an = -6 n + 1 c. an = 6 n -5 d. an = -6 n + 5
Question 3 You are planning a vacation. The hotel you are going to stay at charges $129 per night. This can be represented by the function p(h) = 129 h.

Question 7 Adam earns $75 per week mowing lawns. This can be represented by the function f(x) = 75 x. Each week he deposits this money into his bank account. At the beginning of January his bank account had a balance of $500 in it. Adam also makes a $45 withdrawal each week. The withdrawals from his account can be represented by the function f(x) = 500 - 45 x. Write a function that can be used to represent his bank balance after n months, including his monthly deposit and withdrawal. A) B) C) D) f(n) = 500 - 30 n f(n) = 500 + 30 n f(n) = 12(500 -30 n) f(n) = 500 - (75 n-45 n)
