Question

Troy is going to spain and needs to convert his dollars to euros. He knows that when he goes, $5.00 is equivalent to about 3.45 euros. Find the unit rate of euros per dollar.

Answer 1

As the question says that Tory knows for $5 he will get 3.45 euros.

Now for the euro trip he needs to know the rate of conversion or the rate of euros per dollar.

To find the rate of conversion we need to use unitary method.

As we know that at the given rate he gets,

3.45 euros for $5

or the other way around

`\$5=3.45` euros

Now, using the unitary method we get,

`\$1=(3.45)/(5) =\0.69` euro

Therefore, at the given rate we can see that for each dollar Tory would get 0.69 euro.
