  1. UNIT 2: WORD PROBLEM WORKSHEET # 1.) The equation C(r) = 4 r + 10 represents the cost C(r) at the county fair based on the number of rides, r. (a.) Jake has $ 18 in his pocket. How many rides can he go on? 4 r + 10 = 18 r = 2 - 10 - 10 4 r = 8 4 4

  2. UNIT 2: WORD PROBLEM WORKSHEET # 1.) The equation C(r) = 4 r + 10 represents the cost C(r) at the county fair based on the number of rides, r. (b.) If Jake wants to ride 10 rides, how much money does he have to borrow from his friends? 4 (10) + 10 = C (r) 40 + 10 = C (r) 50 – 18 = amt. to borrow 50 = C (r) 32 = amt. to borrow

  3. UNIT 2: WORD PROBLEM WORKSHEET # 2.) The cost of a pizza is based on the number of toppings plus $ 8. The cost of a 5-topping pizza is $ 14.25. How much would a 3-topping pizza cost? Let x = cost of one topping 5 x + 8 = 14.25 x = 1.25 = cost of one topping - 8 - 8 5 x = 6.25 3 (1.25) + 8 = 3.75 + 8 = 11.75 = cost of 3-topping pizza 5 5
