Final answer:
After accounting for one deposit and two checks, Sun-Hei's ending balance on her checking account statement is $115.22.
Step-by-step explanation:
To determine Sun-Hei's ending balance on her checking account statement, we need to calculate the changes to her initial balance based on the transactions listed. We'll start with her beginning balance and account for her deposit and checks written:
- Beginning balance: $210.47
- Deposit: +$120.00
After the deposit, her balance would be:
$210.47 + $120.00 = $330.47
Next, we need to subtract the amounts of the two checks she wrote:
- Check for $70.02
- Check for $145.23
Subtracting these from her balance gives us:
$330.47 - $70.02 - $145.23 = $115.22
Therefore, Sun-Hei's ending balance is $115.22.
