C is correct. re=r0+(r0−r(1−t)(),anwacc=()r1−t)+(EV)rer_e=r_0+(r_0-r_(1-t)(\fr),an\r_{wacc}={(\fr)}r_1-t)+{(\frEV)}r_ere=r0+(r0−r)(1−t)(E),anwacc=(V)r(1−t)+(VE)re re=r0+(r0−r(1−t)()r_e=r_0+(r_0-r_(1-t)(\fr)re=r0+(r0−r)(1−t)(E) =10%+(10%-6%)(1-30%)(0.60)=10%+1.68%=11.68% Therefore, rwacc=()r1−t)+(EV)rer_{wacc}={(\fr)}r_1-t)+{(\frEV)}r_erwacc=(V)r(1−t)+(VE)re (0.61.6)(6%)(1−0.3)+(1.01.6)(11.68%)=1.58%+7.3%=8.88%{(\frac{0.6}{1.6})}(6\%)(1-0.3)+{(\frac{1.0}{1.6})}(11.68\%)=1.58\%+7.3\%=8.88\%(1.60.6)(6%)(1−0.3)+(1.61.0)(11.68%)=1.58%+7.3%=8.88% r0等于10％从哪里看出

题目中有D/E=0.6=0.6/1，D/V=D/(D+E)=0.6/(0.6+1)=0.375，E/V=E/(E+D)=1/(0.6+1)=0.625，加油~
