Store A sells silver wire for $8.00 per yard. Store B sells silver wire by the spool for $8.00 per spool. The cost of wire at either store can be modeled by the
function C(n) = 8n, where n is the number of yards for Store A and n is the
number of spools of wire for Store B.
The domain of C(n) = 8n is all real numbers.
For each store, drag all the additional restrictions needed on values of n for C(n)
to model each situation.
