You can put this solution on YOUR website!
With 100 stores, the total sales S = 25000%2A100=2500000 dollars per store per week
For 0 additional stores, the total sales is as given above.
For one additional store, sales will decrease by $650
So for N additional stores it will decrease by 650%2AN from the initial value given above
So the equation is S+=+2500000+-+650%2AN
