Answer to Problem 39E
0.86
Explanation of Solution
Given information:
The variables represents as follows:
56 | 50 |
76 | 67.2 |
MPC = Marginal propensity to consume
When MPC is 0.7, the value of
Calculation:
Since 0.7 MPC means, the value of
Thus, the equation for MPC can be written as follows:
Put the values of x and y in the above equation to evaluate MPC as follows:
Thus, the value of MPC is 0.86.
b.
To find: the additional dollars spend by the average family.

Answer to Problem 39E
Explanation of Solution
Given information:
The variables represents as follows:
56 | 50 |
76 | 67.2 |
Marginal propensity to consume, MPC = 0.86
The condition given is that x increases $1805.
Calculation:
The equation of MPC is as follows:
Plug in the given values to evaluate y as shown below.
Thus, the additional consumption expenditure of an average family increases by
c.
To find: MPS.
c.
Answer to Problem 39E
0.14
Explanation of Solution
Given information:
MPC = Marginal propensity to consume
MPS = Marginal propensity to save
MPC = 0.86
Calculation:
Put the value of MPC in the given equation to evaluate MPS as follows:
Thus, the MPS is 0.14.
d.
To find: the additional dollars saved by the average family.
