Help! I'm in 6th grade and I'm lost in this word problem...

Question

Colin made 4 dozen cookies more than Hubert. If Colin made 120 cookies, how many did Hubert make in total?

Answer 1

4 dozen = 4x12 = 48 cookies

C = 48 + H Colin made 48 more than Hubert

C = 120, Colin made 120

120 = 48 + H

subtract 48 from both sides

120-48 = 48+H - 48 = H

H = 120-48 = 72 cookies made by Hubert
