Jason’s bank account balance was $300. He paid 1/4 of his bills. Now, his account balance is -$50. Which equation can be used to find x, the total dollar amount of his bills?

A. 1/4x + 300 = -50
B. -1/4x - 300 = -50
C. -1/4x + 300 = -50
D. 1/4x - 300 = -50

Jason paid 1/4 of his bills from his bank account balance of $300, resulting in a balance of -$50.

To find the total dollar amount of his bills, we need to subtract the remaining balance of -$50 from the initial balance of $300, denoted by x.
Therefore, the equation that can be used to find x is: 300 - 1/4x = -50.

None of the given choices accurately represent this equation.
