3. A tourist named Mr. Lopez from Chile visited Arlington and bought a ticket for the Dallas Cowboys game. During his stay, he also paid for his hotel, meals, and various items from local shops, which totaled $4000. What is the estimated increase in US exports resulting from Mr. Lopez's visit? What is the estimated increase in Chile's imports due to Mr. Lopez's US visit?

4. During his visit to Arlington, Mr. Lopez, a tourist from Chile, bought a pizza from Pie Five Pizza, located on Spaniolo Dr. This transaction can be considered as an export of the pizza to Chile without the need for Pie Five to pay for transportation costs. Instead of Pie Five delivering the pizza to Chile and incurring transportation expenses, Mr. Lopez personally went to Pie Five on Spaniolo Dr. and picked it up. To cover the transportation charge, Mr. Lopez paid for it himself. As a result, this transaction contributed to the increase in our exports in the same way that shipping pizza to Chile would have. The only difference is that Mr. Lopez bore the transportation cost, not Pie Five.

Do you agree with this? Explain.
