The question is incomplete. The complete question is stated below.

If the marginal propensity to consume is equal to 0.85, then a $500 increase in disposable income leads to a:

a. $400 increase in consumption spending

b. $75 increase in consumption spending

c. $425 increase in personal saving

d. $75 increase in personal saving

If a $500 increase causes an increase of $425 in consumer spending, the rest of $75 is the increase in personal saving. Thus, option D is the correct answer.

Explanation:

The marginal propensity to consume or MPC is the percentage of the additional income that will be used for consumption spending. It is a concept that is used to calculate how much of an increase in income will be used in consumption and saving. The formula to calculate MPC is,

MPC = Change in consumer spending / Change in income

0.85 = Change in consumer spending / 500

500 * 0.85 = Change in consumer spending

Change in consumer spending = $425

If a $500 increase causes an increase of $425 in consumer spending, the rest of $75 is the increase in personal saving.

going on the gulag might you to find a better answer for that problem
