13 10 points Sklppea eBook prlnt References (Advanced Analysis) Linear equations for the consumption and saving schedules take the general form C: a4 and savings S: a + (I b) Y, where C, S. and Yare consumption, saving, and national income, respectively. The constant a represents the vertical intercept, and b is the slope of the consumption schedule. a. Use the following data to determine numerical values for a and b in the consumption and saving equations: National Income (Y) 2 aea 600 8e Consumption (C) $120 600 760 Instructions: If you are entering any negative numbers, be sure to include a negative sign (-) in front of those numbers. (Click to select) b. What is the ec (Click to select) Of b? What is the economic meaning of (I-b)? (Click to select) v c. Suppose that the amount of saving that occurs at each level of national income falls by $20 but that the values of b and (1 - b) remain unchanged. Restate the saving and consumption equations for the new numerical values, and cite a factor that might have caused the change. 13 of 25 p Type here to search
