Question

This morning, Elena wrote a check in the amount of $42.50. This brought her balance down to –$14.25. Suppose n represents Elena's balance before she wrote the check.



Which equation can be used to represent this situation?



A.


n – 14.25 = 42.50


B.


n + 42.50 = –14.25


C.


n – 42.50 = –14.25


D.


n – 14.25 = –42.50

Answer 1

n represents Elena's balance before she wrote the check. The check she wrote was for 42.50, so she deducted or took away 42.50 from her balance, which translates to n - 42.50. Her balance after this transaction was -14.25. So in all, this can be translated to n - 42.50 = -14.25
