Answer 1

37 and half dollars

Explanation:

Setup a proportion.

Line up the information so it is neatly categorized.

10 euros = 15 dollars

25 euros = x dollars

This tells you how to setup your proportion.

`(10)/(25)=(15)/(x)`

Cross multiply:

`10x=15(25)`

Simplify the right hand side:

`10x=375`

Divide both sides by 10:

`x=(375)/(10)`

Simplify right hand side:

`x=37.5`

`x=37.50 \text{ dollars }`
