Determine the effect on each company's net income if sales decrease by $15\%$ and if sales increase by $10\%.$ Assume that sales fluctuations are attributable to changes in units sold. Do not prepare income statements. $($Round answers to $2$ decimal places, e$.$g$.10\mathrm{.}52.$ If $\%$ change is negative, enter amount with either a negative sign or parenthesis, eg$.-10\mathrm{.}52$ or $(10\mathrm{.}52).)$
