Help Save a. Use the following data to determine numerical values for a and b in the consumption and saving equations: 6 National Income (Y) Consumption (C) $0 $60 100 140 200 220 300 300 03:49:00 400 380 Instructions: If you are entering any negative numbers, be sure to include a negative sign (-) in front of those numbers. C= $ S= $ b. What is the economic meaning of b? MPC What is the economic meaning of (1-b)? MPS 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. Instructions: If you are entering any negative numbers, be sure to include a negative sign (-) in front of those numbers. C = $ S = $[ Which of these factors might have caused this change? An increase in ti +
