Please answer this question now and I'll make you brainliest, etc: Marcellus is making a deposit that will leave him with a balance of $381. He noticed that if he added $54 to the amount he started with in his account and then tripled the sum, he would get the new amount. How much did Marcellus originally have in his account?

Part A: Which equation represents the situation?

A. 3m + 54 = 381, where m represents the amount originally in his account

B. 3(m + 54) = 381, where m represents the amount originally in his account

C. 3m − 54 = 381, where m represents the amount originally in his account

D. 3(m − 54) = 381, where m represents the amount originally in his account
