Zack bought a coat for $69.78 .he paid with a $100 bill and received $26.73 in change. how much was the sales tax? plz ill give 10 points

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
