Let’s solve this step by step.
We are tracking Doni’s checkbook from October 1 to October 31. We start with a beginning balance of $986.25 (as told in the instructions).
Then we go through each transaction one by one, adding deposits and subtracting payments/debits.
---
Starting Balance: $986.25
---
Transaction 1: Oct 1 — Paycheck deposit $556.75 → CHECK 1002
This is money coming IN → ADD
$986.25 + $556.75 =
$1,543.00
---
Transaction 2: Oct 3 — Spent $75.00 on shoes → CHECK 1003
Money going OUT → SUBTRACT
$1,543.00 - $75.00 =
$1,468.00
---
Transaction 3: Oct 4 — Spent $25.01 on sweater + $22.49 on jeans → CHECKS 1004 & 1005
Total spent: $25.01 + $22.49 =
$47.50
Subtract that:
$1,468.00 - $47.50 =
$1,420.50
---
Transaction 4: Oct 15 — Grandmother gave $200.00 for birthday → CHECK 1006
Money coming IN → ADD
$1,420.50 + $200.00 =
$1,620.50
---
Transaction 5: Oct 20 — Paid phone bill $18.14 → CHECK 1007
Money going OUT → SUBTRACT
$1,620.50 - $18.14 =
$1,602.36
---
Transaction 6: Oct 28 — Groceries $85.42 → CHECK 1008
Money going OUT → SUBTRACT
$1,602.36 - $85.42 =
$1,516.94
---
Transaction 7: Oct 29 — Concert tickets $38.00 → CHECK 1009
Money going OUT → SUBTRACT
$1,516.94 - $38.00 =
$1,478.94
---
Transaction 8: Oct 31 — Rent payment $850.00 → CHECK 1010
Money going OUT → SUBTRACT
$1,478.94 - $850.00 =
$628.94
---
So, final balance at end of October =
$628.94
But the question asks:
> What is the total change in Doni’s account?
That means: How much did the balance go up or down from start to finish?
Start: $986.25
End: $628.94
Change = End - Start
= $628.94 - $986.25
=
-$357.31
Negative means the account went DOWN by $357.31.

Final Answer:
-357.31
