Suppose the population is 300 million people, the labor force is 200 million people, the number of people employed is 185 million, and the working-age population is 170 million people. What is the unemployment rate?

A) Consumption, investment, and net exports will rise. B) Consumption will rise, but investment and net exports will fall. C) Consumption and investment will rise, but net exports will fall. D) Consumption will fall, but investment and net exports will rise.

Suppose the governor of California has proposed increasing toll rates on California's toll roads, and has presented two possible scenarios to implement these increases. Following are projected data for the two scenarios for the California toll roads:

Scenario 1: Toll rate in 2015: $10.00. Toll rate in 2019: $22.50 For every 100 cars using the toll roads in 2015, only 81.6 cars will use the toll roads in 2019. Scenario 2: Toll rate in 2015: $10.00. Toll rate in 2019: $17.50 For every 100 cars using the toll roads in 2015, only 96.2 cars will use the toll roads in 2019. a. Using the midpoint formula, calculate the price elasticity of demand for Scenario 1 and Scenario 2. b. Assume 10,000 cars use California toll roads every day in 2015. What would be the daily total revenue received for each scenario in 2015 and in 2019? c. Is demand under Scenario 1 and under Scenario 2 price elastic, inelastic, or unit elastic. Briefly explain. (For above questions, assume that nothing other than the toll change occurs during the time frame listed that would affect consumer demand.) What will be an ideal response?
