Question

Thor is reconstructing his expenses for the past two weeks. You can see the records of his expenses. Thor's bank statement says that he has an ending balance of $86. What is Thor's starting balance?

Answer 1

The table shows the total amount Thor spent over the past 2 weeks.

The total amount Thor spent can be gotten by adding the costs of all the transactions he made over the period.

Amount Spent:

`TC=25+35+55+15+13=143`

The starting balance can be calculated as:

`SB=TC+EB`

where

`\begin{gathered} SB=\text{ Starting Balance} \\ TC=\text{ Transaction Costs} \\ EB=\text{ Ending Balance} \end{gathered}`

Since the ending balance is given to be $86, we can calculate the starting balance to be:

`SB=143+86=229`

Thor's starting balance is $229.
