Answer :
Answer:
Part 1) [tex]E=0.85\ euros[/tex]
Part 2) [tex]D=1.18\ dollars[/tex]
Step-by-step explanation:
The correct question is
We can calculate E, the amount of euros that has the same value as D U.S. dollars, using the equation E=(17/20)D .
How many euros have the same value as 1 U.S. dollar?
How many U.S. dollars have the same value as 1 euro?
Part 1) How many euros have the same value as 1 U.S. dollar?
we have
[tex]E=\frac{17}{20}D[/tex]
so
For D=1
substitute in the given equation and solve for E
[tex]E=\frac{17}{20}(1)[/tex]
[tex]E=0.85\ euros[/tex]
Part 2) How many U.S. dollars have the same value as 1 euro?
we have
[tex]E=\frac{17}{20}D[/tex]
so
For E=1
substitute in the given equation and solve for D
[tex]1=\frac{17}{20}D[/tex]
Multiply by 20/17 both sides
[tex]D=(20/17)(1)\\D=1.18\ dollars[/tex]
