If the marginal propensity to save is 0.25, a $15 billion increase in government spending will lead to an increase in national i
Greeley [361]

Based on the marginal propensity to save, MPS , the national income will increase by a maximum of $20 billion.

<h3>What is marginal propensity to save?</h3>

Marginal propensity to save (MPS) is a measure of how savings will change, given a change in income.

Marginal propensity to save is related to marginal propensity to consume, MPC by the formula:

  • MPS + MPC = 1

Grom the given value of MPS,

MPC = 1 - 0.25

Therefore, MPC = 0.75

Also, the formula for calculating marginal propensity to consume is given as:

  • Marginal propensity, MPC = ΔC/ΔY

Where:

  • ΔC is a change in consumption
  • ΔY is a change in income

ΔY = ΔC/MPC

ΔY = $15 billion/0.75

ΔY = $20 billion

Therefore, the national income will increase by a maximum of $20 billion.

What is the electrical pathway of the heart, in order? NOTE- this includes pacemaker and conduction components.
s2008m [1.1K]

Answer:

The correct answer will be option A.

Explanation:

The electrical impulses are generated in the sino-atrial node or SA node, a mass of cells which generates impulse in the upper atrium.  

This electrical impulse transmits from the sino-atrial node to the atrio-ventricular node in the lower portion of the upper atrium through the internodal pathway- the pathway composed of atrial cells.

Once the impulse reaches the AV node, it is transferred to the ventricular portion of the heart through Bundle of His presence in the ventricular septum. This bundle of his divides into left and right ventricles through bundle branches and stimulates both the ventricles.

Thus, option-A is the correct answer.
