Question 1076781: Suppose that you are planning a trip to Europe, so you need to obtain some euros. The amount received in euros varies directly with the amount in U.S. dollars. Your friend just converted $600 into 405 euros.
(a) Write a linear function that relates the number of euros E to the number of U.S. dollars d.
(b) If you convert $700 into euros, how many euros will you receive?
(c) Graph the relation between euros and U.S. dollars.

$600=405 e
$1=0.675 e, dividing both sides by 600.
$700=0.675*700=472.5 e
1 e= $1.481
