1 US Dollars is equal to 0.85 euros.

Explanation:

Given formula to calculate the amount of Euros:

$E=\dfrac{17}{20}D$ , where D denotes  the amount of US dollars.

When D = 1 US dollar, then we have

$E=\dfrac{17}{20}(1)\\\\\Rightarrow\ E=\dfrac{17}{20}\\\\\Rightarrow\ E=\dfrac{17\times5}{20\times5}=\dfrac{85}{100}\\\\\Rightarrow\ E=0.85$

Hence , 1 US Dollars is equal to 0.85 euros.
