Activity #10 Linear Models 3. The cost for a rental car is $49.95 per day plus a flat fee of $31.95 for insurance. The equation, C = 49.95x + 31.95 represents the total cost, C (in dollars), to rent the car for x day. C Cost to Rent a Car 600 500 C= 49.95x + 31.95 400 300 200 100 Number of Days a. Identify the slope and interpret its meaning in the context of the problem. b. Use the equation to determine how much it would cost to rent the car for 1 week. 4. A beverage company rents a booth at an art show to sell lemonade. The daily cost to rent the booth is $65. Each lemonade costs $0.50 to produce. a. Write a linear equation to compute the total cost, y, for 1 day if x lemonades are produced. b. Use the equation to compute the cost for one day if 350 lemonades are produced. 2. Is whaty c. Use the equation to compute how many lemonades can be produced if the total cost for one day is $200.Activity # 10 Linear Models 5. The cost for 7 dance lessons is $82. The cost for 11 lessons is $122. a. Write a linear equation to find the total cost C for f lessons. b. Use the equation to find the cost of 4 lessons. 6. It is 76 . F at the 6000-foot level of a mountain, and 49 . F at the 12,000-foot level of the mountain. a. Write a linear equation to find the temperature T at an elevation x on the mountain, where x is in thousands of feet. b. Use the equation to find the temperature at 8500 feet. O.'The following ordered pairs give the population of the U.S. colonies from 1700 to 1770. Let x represent the year, where x = 0 corresponds to 1700, x = 5 corresponds to 1705, and so on. Let y represent the population of the colonies. (0. 251000) (10, 332000) (20, 466000) (30. 629000) (40, 906000) (50, 1171000) (60, 1594000) (70, 2148000) g 1. What was the population in 1750? . 2. in what year was the population 1,594,000? .\\ 3. interpret the meaning of the ordered pair (10, 332000) and write a sentence in the context of the problem using appropriate units
