Answer 2

`D=\$1.18`

Explanation:

we have the expression

`E=(17)/(20)D`

where

E is the amount in Euros

D is the amount in dollars

Solve for D

That means----> isolate the variable D

Multiply by 20/17 both sides

`D=(20)/(17)E`

For E=1 euro

substitute and solve for D

`D=(20)/(17)(1)`

`D=\$1.18`
