euros are currency used in several European countries . on one day in October 2005, you could exchange 3$ for about 2.5 euros. how many dollars would you have to needed to get 8 euros?

Respuesta :

We Can Represent This With A Fraction Relationship. 
[tex] \frac{3}{2.5} = \frac{X}{8} [/tex]
Multiply Means And Extremes. 
24 = 2.5x
Divide Both Sides By 2.5
24/2.5 = x
24/2.5 = 9.6
9.6 = x
So, It Would Take $9.60 for 8 euros.
