Answer: Balance = (X + 391.25) dollars.
Step-by-step explanation: Base on the information provided.
Let assume that Ms Biola initial amount in checking account = X
500 dollars was transferred into the account.
She made 150 dollars per day from 10th to 15th. I.e six day
150×6 = 900 dollars
148.5 dollars was also deposited
The Total amount
T = X + 500 + 900 + 148.5
= X + 1548.5
She wrote a check of 157.25 and settled Bill's of 1000 dollars
The balance at the end of March will be:
Balance = X + 1548.5 - 1157.25
Balance = (X + 391.25) dollars.
