Problem Explanation

Explanation:

We need to round the purchaseAmount to the nearest multiple of 10 and then subtract this rounded amount from the initial bank account balance of 100 dollars to get the final balance.
We can round the purchaseAmount using the formula (purchaseAmount + 5) / 10 * 10.
The final balance will be calculated as 100 - roundedAmount.
