Use both numerical and graphical methods to find the multiplier effect of the following shift in the consumption function in an economy in which investment is always $220, government purchases are always $100, and net exports are always 2-40. (Hint: What is the marginal propensity to consume?)
Consider the hypothetical country of Kejimkujik. Suppose that national income in Kejimkujik is $300 billion, households pay $100 billion in taxes, household consumption is equal to $160 billion, and the marginal propensity to consume (MPC) is 0.6.
On the following graph, use the blue line (circle symbol) to plot the economy's consumption function.

Suppose now that Kejimkujik’s national income increases to $330 billion. Assuming the amount paid in taxes is fixed at $100 billion and that MPC = 0.6, what is the new amount of household consumption?
$148 billion
$219.4 billion
$220.6 billion
$178 billion
Need help with this, please show me where to plot the two points on the graph as well. Thanks!
