For two weeks, Gabrielle raised money by selling magazines. She raised $72 during the second week, which brought her total to $122. Write and solve an equation to find how much Gabrielle raised during the first week. Show that your answer is reasonable.

Ok so if Gabriel’s total is 122$ and she made 72$ The second week your equation would be 122= 72x  now if you subtract 72 from both sides that cancels out the 72 leaving you with 50=x.

answer: -2+√x,-2-√x
