if investment increases by $100 and, as a result, GDP ultimately increases by $200, the multiplier equals?

To determine the multiplier in this scenario, we need to divide the change in GDP by the change in investment.

The formula for the multiplier is:

Multiplier = Change in GDP / Change in Investment

In this case, the change in GDP is $200 and the change in investment is $100.

Therefore, the multiplier would be:

Multiplier = $200 / $100
= 2

So, the multiplier in this scenario is 2.

To calculate the multiplier, you can use the following formula:

Multiplier = Change in GDP / Change in Investment

In this case, the change in investment is $100 and the change in GDP is $200.

Multiplier = $200 / $100

Multiplier = 2

Therefore, the multiplier in this scenario is 2.
