Last year, Martin Inc. reported $$11,109$ of sales, $$4,852$ of operating costs other than depreciation, and $$1270$ of depreciation. The company had $$3,500$ of bonds outstanding that carry a $7\mathrm{.}45\%$ interest rate, and its federal$-$plus$-$state income tax rate was $35\%.$ This year's data are expected to remain unchanged except for one item, depreciation, which is expected to increase by $$571.$ By how much will the depreciation change cause:

$(1)$ the firm's net income to change? $

$(2)$ its operating cash flow to change? $

Notes:

$($i$)$ To get the proper sign $(+/-),$ please subtract last year's value from this year's value $($i$.$e$.$ This Year $-$ Last Year$)$;
