(1.8 dollars)/(1 euro) = (x dollars)/(200 euros) What is the value of x?. How many dollars must he give? (1.8 dollars)/(1 euro) = (x dollars)/(200 euros) What is the value of x?

Answer 1

Joe must give 360 dollars to get 200 euros, given the exchange rate of 1.8 dollars per euro, determined by the cross-multiplication (1.8 dollars/euro × 200 euros = 360 dollars).

Step-by-step explanation:

Joe wants to exchange dollars for euros and needs to determine how many dollars he must give to get 200 euros given an exchange rate of 1.8 dollars per euro. To find the amount in dollars x that Joe needs, we can set up the proportion (1.8 dollars)/(1 euro) = (x dollars)/(200 euros).

We solve for x by cross-multiplying:

1. Multiply 1.8 dollars by 200 euros to find the total dollar amount Joe needs.
2. The calculation is 1.8 dollars/euro × 200 euros = 360 dollars.
3. Therefore, Joe must give 360 dollars to get 200 euros.

This calculation is relevant for Joe or any individuals dealing with currency exchange and requiring an understanding of how changes in exchange rates affect the amount of one currency needed to purchase another.
