Answer:
Supply of euros will increase and the euro will depreciate
Step-by-step explanation:
The euro will depreciate against the US dollar. This means that you will need more euros (or more euro cents) to buy one US dollar.
Both the euro and the US dollar are free floating currencies, which means that their value is given by the supply and demand. Since the supply of euros increases, as well as the demand for US dollars increases, the US dollar will appreciate against the euro.
