Answer:
D) increase; decrease
Step-by-step explanation:
in order to appreciate the currency by $0.10, the interest rates need to be increased. This will encourage people to save more and thus increase the demand for gizmo that will increase the exchange rate.
This increased interest rate will also decrease the capital outflow out of the country as more people will be willing to take advantage of higher interest on savings in the country than investing outside of the country to leverage opportunities. Thus option D is the right choice.
Hope that helps.
