There are no expressions to choose from, but it should look something like:

y= total cost= $74.50
x= number ordered= 10
c= cost per lunch= 74.50/10= $7.45

The more lunches that are ordered, the higher the total will go. y depends on what x is.

y= $7.45x
OR
$74.50= 10c

CHECK:
$74.50= $7.45 per lunch * 10 lunches
$74.50= $74.50

ANSWER: y= $7.45x OR $74.50= 10c

Hope this helps! :)
