1) 2.8 USD

Explanation:

I) First of all, the nominal exchange rate describes how much foreign currency can be exchanged for a unit of domestic currency, but the real exchange rate indicates how much the goods and services in the domestic country can be exchanged for the goods and services in a foreign country.

If 1USD=0.89CAD, then 1 CAD=1/0.89=1.12USD

Then 2.5 CAD = 2.5*1.12= 2.8 USD so we will need 2.8 USD to get 2.5 CAD.

II) As we know, the movement of the money supply is the responsibility of the monetary policy activities by central banks. There are several methods:

1) Modifying Reserve Requirements: means that it is possible to influence by modifying the reserve requirements to increase or decrease the money supply. More deeply, this modification refers to the amount of funds banks have to keep against deposits in bank accounts. By lowering the reserve requirements, banks are able to loan more money, which grow the overall supply of money in the economy. Conversely, by increasing the banks' reserve requirements, it will be possible to decrease the size of the money supply.

2) Changing Short-Term Interest Rates: means that it is possible to change the interest rates in short terms to alter the money supply. It’s all about the changing the discount rates. By lowering the rates, it is possible increase the money supply and boost economic activity.  

3) Conducting Open Market Operations: means that it is possible to increase or decrease the money supply conducting open market operations, which affects the funds rate. So the authority who deals with the monetary policy buys and sells government securities in the open market. If the authority wants to increase the money supply, it will purchase government bonds as a result this supplies the securities dealers who sell the bonds with cash, increasing the overall money supply. However, if the authority wants to decrease the money supply, it will send bonds from its account, thus taking in cash and removing money from the economic system as a result, adjusting the funds rate is a heavily anticipated economic event.
