Mrs. Femandez starts out with $255 in her checking account. She deposits $35 on Monday. Tuesday afternoon she writes a check for $75
Which expression could be used to find Mrs. Femandez's new account balance?

255+35-75

Step-by-step explanation:

Since we are trying to find the account balance, we consider anything in or going to the account to be positive.

255 is positive since it is in the account

35 is positive since it is going into the account

75 is negative because it is going out of the account

so the final expression to express the amount is the checking account would be 255+35-75
