Graham's monthly bank statement showed the following deposits and withdrawals: - $25.20, $52.75, - $22.04, - $8.50, $94.11. If Graham's balance in the account was $47.86 at the beginning of the month, what was the account balance at the end of the month?

So the problem start at the first month where Graham's bank has 47.86$

From there, it is juste a question of subtracting and adding.

47.86 - 25.20 = 22.66

22.66+52.75 = 75.41

75.41 - 22.04 = 53.37

53.37 - 8.50 = 44.87

44.87 + 94.11 = 138.98 (this is the last transaction)

So at the end of the month, the balance will be of 138.98$
