Answer:
He started the day with 7.65
Step-by-step 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
