Answer:
The answer is that this month’s fuel oil bill exceed last month’s bill by US$ 27.10
Explanation:
Let's review extensively the Rick and Koby's bank account activity to answer the question correctly:
Previous balance US$ 528.76
Deposits this month:
Automatic deposit US$ 400.oo
Interest earned US$ 3.56
Balance = 932.32
Withdrawals this month:
Checks processed US$ 416.79
Fuel oil bill = x
Balance = US$ 228.58
For calculating the fuel oil bill, we solve the following equation:
932.32 - 416.79 - x = 228.58
515.53 - x = 228.58
- x = 228.58 - 515.53 (Subtracting 515.53 at both sides)
- x = - 286.95
x = 286.95
286.95 - 259.85 = 27.10
This month's fuel oil bill was US$ 286.95 and exceeds by US$ 27.10 last month's bill.
