Question 1 As a fundraiser, the band is selling cookies. The cost to make each cookie can be written as c(x) = 0.25x and the functions that represents the amount they sell the cookie for can be written as s(x) = 2x. What function represents the profit, P(x), for each function? A)P(x) = 0.5x + 1 B)P(x) = 0.5x 2 + x C)P(x) = 2.25x D)P(x) = 1.75x - 0.5

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) = 129h. The car rental company charges a $50 insurance fee plus $79 per day. This can be represented by the function p(c) = c. Write a function p(v) to represent the total charges for your hotel and car rental. A)p(v) = 258v B)p(v) = v C)p(v) = 129(79v + 50) D)p(v) = 50(129h + 79c)

Question 7 Adam earns $75 per week mowing lawns. This can be represented by the function f(x) = 75x. 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) = x. Write a function that can be used to represent his bank balance after n months, including his monthly deposit and withdrawal. A)f(n) = n B)f(n) = n C)f(n) = 12(500-30n) D)f(n) = (75n-45n)

Question 11 A function that can be used to model the cost of producing x t-shirts is c(x)= x, and the function that can be used to model the amount of money to be made from selling x t-shirts is m(x) = 20x. Write a function p(x) to represent the total profit of selling x number of shirts. A)p(x) = x B)p(x) = 13x - 10 C)p(x) = 27x - 10 D)
