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 needed to get 8 euros.
set up ratio
3/2.5 = x/8
2.5x = 24
x = 9.6
$9.60 for 8
3/2.5 = x/8
Cross multiply and solve for x.
2.5x = 24
x = 24/2.5
x = 9.60

To find out how many dollars you would have needed to get 8 euros, we can use the exchange rate given: $3 for about 2.5 euros.
First, we need to find the exchange rate in dollars per euro. We can do this by dividing the number of dollars by the number of euros: $3 / 2.5 euros = $1.2 per euro.
Now, to find how many dollars you would need to get 8 euros, we can multiply the number of euros by the exchange rate in dollars per euro: 8 euros x $1.2 per euro = $9.6.
Therefore, you would have needed about $9.6 to get 8 euros.
