Calculating Cash FLows?

In a particular year, a firm has revenues of $6,500, cash expenses of $4,000, and depreciation charges of $1,500. If the tax rate is 30%, what is the firm's cash flow from operations for that year?

I ended up getting $2,500 because I did not include the Depreciation charges. But this is confusing me because

6500-4000=2500

Then I would usually do 2500- (.30*1500) = $2050

but it is not one of my options
