Answer:
0.64
Explanation:
Marginal propensity to consume is given by the ratio of the change in consumption spending to the change in income.
In this scenario, the change in consumption spending is:
[tex]\Delta CS = \$7,040-\$6,720\\\Delta CS = \$320[/tex]
The change in income is:
[tex]\Delta I = \$8,500-\$8,000\\\Delta CS = \$500[/tex]
The marginal propensity to consume for this economy is:
[tex]MPC=\frac{\Delta CS}{\Delta I}=\frac{\$320}{\$500} \\MPC =0.64[/tex]
The answer is 0.64.
