Bridge and Sarah have $3 between them. If Bridget has 50 cents more than Sarah, how many cents does Sarah have?
Thoughts? Step-by-step reasoning:
User
Let X be the amount of money Sarah has, so Bridget has X + 50 cents. We know that Sarah and Bridget combined have $3, or 300 cents, so X + X + 50 = 300. We therefore know that 2X = 250. So Sarah has 250 / 2 = 125 cents.
Thus, the answer is 125.
