Answer 2

Part 1)
`E=0.85\ euros`

Part 2)
`D=1.18\ dollars`

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

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

so

For D=1

substitute in the given equation and solve for E

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

`E=0.85\ euros`

Part 2) How many U.S. dollars have the same value as 1 euro?

we have

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

so

For E=1

substitute in the given equation and solve for D

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

Multiply by 20/17 both sides

`D=(20/17)(1)\\D=1.18\ dollars`
