Linear equations for the consumption, saving schedules take the general form C = a+ bY and S= -a + ( 1 - B) Y, where C, S , and Y are consumption, saving, and national income, respectively. The constant a represents the vertical intercept, and b represents the slope of the consumption schedule.
A) use the following data to substitute numerical values for A and B in the consumption and savings equation 
B) what is the economic meaning of B? Of (1-b)?
C) suppose that the amount of saving that occurs of 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 inserting the new numerical values, and cite a factor that might have caused the change.
Suppose that Y=MX+b, where Y=consumption, b=consumption at zero income, M=slope, and X=income(i) Are Y and X positively related or are they negatively related?(ii) If graphed, would the curve for this equation slope upward or slope downward?(iii) Are the variables Y and X inversely related or directly related?(iv) What is the value of Y if b=10, M=.50, and X=200?(v) What is the value of X if Y=100, b=10, and M=.25?

First, the graph tells us the amount a person with a certain income is likely to spend on a car, and second, it tells us the probable income of a person who spent a certain amount on a car. For example, if an individual earned $40,000 last year and purchased a new car, you would expect that person to have paid about _________ for the car. Similarly, if someone just paid $25,000 for a car, you could use this graph to estimate that this person's income was probably around __________ .arrow_forwardReal-Time Data Analysis Exercise The following table contains the most recent household expenditure data from FRED*. *Real-time data provided by Federal Reserve Economic Data (FRED), Federal Reserve Bank of Saint Louis.
