Answer:
B) exchange rate
Explanation:
The exchange rate is exactly the way to measure the value between two currencies. Through the exchange rate you will be able to know how much of one currency you can buy with the other. One tip is to think of one of the coins as if it were a commodity. For example, if you want to buy Euros, you think: How much dollar do I need to buy a euro? For this answer, you look at the exchange rate. For example, if the exchange rate is $ 1: € 1, that means that with 1 dollar you can buy one euro. If the exchange rate is 1: € 1.20, that means that with 1 dollar you buy € 1.20. If the exchange rate is $ 1: € 0.8, that means that with 1 dollar you buy eighty euro cents.
