Algebraic method

Prosperous Bank has three support areas $($administration$,$ human resources, and accounting$)$ and three revenue$-$generating areas $($checking accounts, savings accounts, and loans$).$ Monthly direct costs and the interdepartmental support structure are shown below:

Compute the total cost for each revenue$-$generating area of the bank using the algbraic method.

Note: Do not round proportions in your calculations; round your final answer to the nearest whole dollar.

Note: Round your final answers below to the nearest $100$ ; for example, round $8,668$ to $8,700.$
