Answer 1

Answer: 1 U.S.dollar  = 0.85 euro.

1 euro = 1.18 dollars.

Step-by-step explanation:

The given equation: $E=\dfrac{17}{20}D$

, where 'E' is the amount of euros that has the same value as 'D' U.S. Dollars.

At D= 1,

$E=\dfrac{17}{20}=0.85\text{ euro}$

i.e. 1 U.S.dollar  = 0.85 euro.

At E= 1 , we have

$1=\dfrac{17}{20}D\\\\\Rightarrow\ D= 20/17\approx1.18\text{ dollars}$

Hence, 1 euro = 1.18 dollars.
