Answer:The government spending multiplier can be calculated as:
Government Spending Multiplier = 1 / (1 - MPC)
In this case, since the MPC is 0.6, the government spending multiplier will be:
Government Spending Multiplier = 1 / (1 - 0.6) = 1 / 0.4 = 2.5
So, the government spending multiplier is 2.5.
If government spending (G) increases by $20, we can calculate the change in Total Spending using the government spending multiplier as follows:
Change in Total Spending = Government Spending Multiplier * Change in Government Spending
Change in Total Spending = 2.5 * $20 = $50
Therefore, if government spending increases by $20, Total Spending will increase by $50.
