Mary purchased 4 tires by mail order. She paid ​$54.70 per tire plus​ $5.90 per tire for shipping and handling. There is no sales​ tax, because the tires were purchased out of state. She also had to pay​ $7.06 per tire for mounting and balancing. At a local​ store, Mary's total for the 4 tires with mounting and balancing would be ​$324 plus 6​% sales tax.

step-by-step explanation:

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
