Answer:
total=quantity*price per item on that row
New account balance=old account balance plus total on that row
Explanation:
I won't do all of the rows but I will do a couple and explain to you how I got the answer and how you should too:
The total for each row is equal to that row's price per item times that row's quantity.
The amount balance is going to include previous account balance into it. So once you find the total for that row you will take previous account balance and add it to the previous account balance (We are doing adding instead of subtracting because the number we are getting is negative for the total.)
So example:
Second row total is 2(-45.25)=-90.50 so that is what we are adding to 2500.68 or we are subtracting 90.50 from 2500.68 giving us 2410.18
Third row total is 75(-1.39)=-104.25. Third row account balance is 2410.18-104.25=2305.93.
So again total=quantity*price per item on that row
New account balance=old account balance plus total on that row
If you want me to check your forth row to see if you are doing it right, I will.
