YOUR ASSIGNMENT: Factory Lighting ProblemIn this assignment, you may work alone, with a partner, or in a small group. Discuss the results of your work and/or any lingering questions with your teacher. You are deciding whether to light a new factory using bulb A, bulb B, or bulb C. Which bulb would be better to use on the factory floor? Which bulb would be better to use in the break room? To answer these questions, you will compare the energy usage of the three bulbs. The amount of energy the lights use is measured in units of kilowatt-hours. A kilowatt-hour is the amount of energy needed to provide 1000 watts of power for 1 hour. 1. Circle the two bulbs you picked. incandescent Halogen Fluorescent 2. 3. Practice: Summarizing (3 points) Fill in the blanks. The energy usage of a light bulb is a function. The input for the function is _________, measured in hours. The output of the function is energy usage, measured in ____________. Identify the functional relationship between the variables. _________________ is a function of _________________. The graph of the function will show energy usage on the _____________ axis and time on the _______________ axis. 4. Practice: Organizing Information (2 points) Use the data given to complete the table for your first bulb. DATA TABLE A Time (hours) x Energy (kWh) y Point (time, energy) (x, y) 3 10 5. Practice: Organizing Information (2 points) Use the data given to complete the table for your second bulb. DATA TABLE B Time (hours)x Energy (kWh)y Point (time, energy)(x, y) 3 10 6. Practice: Organizing Information (5 points: 1 point for labels, 2 points for each graph) Label the axes of the graph with "Time (hours)" and "Energy (kWh)." Plot the points from Table A on the graph. Connect the points with a line. On the same graph, plot the points from Table B and connect them with a line. 7. Practice: Summarizing (1 point) Classify each of your graphs as increasing, decreasing, or constant. First bulb: ___________________ Second bulb:___________________ 8. Practice: Summarizing (2 points) Fill in the blanks. First bulb: When 3 is the input, the output is _____. When 10 is the input, the output is _______. Second bulb: When 3 is the input, the output is _____. When 10 is the input, the output is _______. 9. Practice: Summarizing (1 point) The workers leave the lights on in the break room for stretches of about 3 hours. Which light bulb would light this room using the least amount of energy? 10. Practice: Summarizing (1 point) The lights in the main room of the factory stay on for stretches of 9 hours. Which kind of light bulb would light this room with the least amount of energy?

Answer:
- free throws: 136
- 2-point: 174
- 3-point: 121
Step-by-step explanation:
Let x represent the number of 2-point field goals Rebecca made. Then the number of 3-point field goals can be represented by t, where ...
x = 2t -68 ⇒ t = (x +68)/2 . . . . . number of 3-point field goals
The number of free throws made was x -38.
Rebecca's total point count was ...
1(x -38) +2x +3(x +68)/2 = 847
9/2x +64 = 847
9/2x = 783
x = (2/9)(783) = 174
x -38 = 136
(x +68)/2 = 121
Rebecca made 136 free throws, 174 2-point field goals, 121 3-point field goals.
