Question

Antonio's checking account currently has a negative balance of −$42.17. Yesterday he made purchases of $3.75 and $12.07. If Antonio's bank charges $34 for overdraft protection, what was his account balance prior to yesterday's transactions?

Answer 1

He started the day with 7.65

Explanation:

Assuming at the beginning of yesterday he had a balance of x

He will be charged 34 dollars since he went negative

x- 3.75 -12.07 - 34 =-42.17

Combine like terms

x -49.82 = -42.17

Add 49.82 to each side

x -49.82+49.82 = -42.17+49.82

x = 7.65
