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.

Isuck at math ; ^; m a student solved this problem and said the answer is 3 feet. chase had a roll of ribbon that contained 7 7/8  feet of ribbon. he cut off one piece that was 3 5/8  feet long and another piece that was 1 1/4  feet from the roll. how much ribbon was left on the roll? is the student's answer reasonable? yes, the answer is reasonable. no, the answer is not reasonable. it should be about 2 feet. no, the answer is not reasonable. it should be about 13 feet. no, the answer is not reasonable. it should be about 4 feet.
