Question Ball Toss Throw the ball at a number then answer that question.

Question 1 As a fundraiser, the band is selling cookies. The cost to make each cookie can be written as c(x) = 0.25x + 0.5 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 + 0.5 D) P(x) = 1.75x - 0.5

Question 2 Which explicit rule describes the sequence below? 1, 7, 13, 19, 25… a n = 6n +1an = -6n + 1an = 6n -5 a n = -6n + 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) = 50 + 79c. Write a function p(v) to represent the total charges for your hotel and car rental. A) p(v) = 258v B) p(v) = 50 + 208v C) p(v) = 129(79v + 50) D) p(v) = 50(129h + 79c)

Question 6 Determine the common ratio and find the next three terms of the geometric sequence 1, -2, 4, -8, … r = 2, a 5 = 16, a6 = 32 a7 = 64 r = -3, a5 = -11, a6 = -14, a 7 = -17 r = -2, a 5 = 16, a 6 = -32 a 7 = 64 r = 3, a 5 = -5, a6 = -2, a7 = 1

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) = 500 - 45x. Write a function that can be used to represent his bank balance after n months, including his monthly deposit and withdrawal. A) f(n) = 500 - 30n B) f(n) = 500 + 30n C) f(n) = 12(500-30n) D) f(n) = 500 - (75n-45n)

Write a function p(x) to represent the total profit of selling x number of shirts. A) p(x) = 10 - 13x B) p(x) = 13x - 10 C) p(x) = 27x - 10 D) p(x) = A) p(x) = 10 - 13x B) p(x) = 13x - 10 C) p(x) = 27x - 10 D)
