Answer:
Disposible income.
Marginal propensity to consume.
Disposible income, marginal propensity to consume.
The consumption will increase by $800
Explanation:
The consumption function shows the relationship between consumption spending and disposible income.
The slope of the consumption function is the marginal propensity to consume.
Changes in consumption can be predicted by multiplying the change in disposible income by the marginal propensity to consume.
Given: MPC = 0.80
Disposible income increases by $1,000
consumption increase = 0.80*$1000
= $800
Therefore, The consumption will increase by $800.
