Last year, Stewart-Stern Inc. reported $11,250 of sales, $4,500 of operating costs other than depreciation, and $1,250 of depreciation. The company had $3,500 of bonds outstanding that carry a 6.5% interest rate, and its federal-plus-state income tax rate was 35%. During last year, the firm had expenditures on fixed assets and net working capital that totaled $2,000. These expenditures were necessary for it to sustain operations and generate future sales and cash flows. This year's data are expected to remain unchanged except for one item, depreciation, which is expected to increase by $725. By how much will the depreciation change cause (1) the firm's net income and (2) its free cash flow to change?
