Mrs.Blakley had 15 6th grade students and they all loved to bother her, so she gave them a problem that would probably get them to leave her alone. The problem was 12(3y + 6).After 2 minutes almost the whole class come up and all have the answers of 15y+18y. Is their answer correct?Solve the problem then tell why.
No the anwer is not correct because they didn't multiply the 3 and 6 by 12.
