Pick some number between $500 and $1500 and assume that the MPC for that state is 0.75. Estimate the total impact on the economy for the state you traveled to based upon your initial spending amount

$750

Explanation:

If I pick $1,000, and the Marginal Propensity to Consume (MPC) is 0.75, it means that while travelling the state, I will have spent $750 on goods and services either produced and traded in that state, or only traded in that state (while having been produced in other place). This is the total impact that I will have made on the economy of this state.

The remaining $250 that I will have saved will only impact the economy of the state if I deposit or invest the money in a financial institution located in the state. If instead, I invest those saving in some other state, or put the money under the mattress in my house (located in another state), my savings will not impact the economy of the state in any way whatsoever.
