Bridge and Sarah have $3 between them. If Bridget has 50 cents more than Sarah, how many cents does Sarah have?
assistant
Define a variable ** Let X be the amount of money Sarah has, so Bridget has X + 50 cents
Write an equation ** We know that Sarah and Bridget combined have $3, or 300 cents, so X + X + 50 = 300
Simplify ** We therefore know that 2X = 250
How many cents does Sarah have? ** So Sarah has 250 / 2 = <<250/2=125>>125 cents
#### 125
