Best ResponseYou've already chosen the best response.0I mean, ifthe answer comes out as 60, it won't be accurate, because the denominator is never equal to zero.

Best ResponseYou've already chosen the best response.2(c 100)/100 = (2c60)/ (c+60) denominator are 100 and c+60 LCM = 100(c+60) multiply both sides with 100(c60) (c100)(c+60) = (2c60)(100) (c100)(c+60) =c^2 +60c 100c 6000 =c^2  40c 6000 (2c60)(100) =200c 6000 (c100)(c+60) = (2c60)(100) c^2  40c 6000= 200c 6000 c^2 40c  6000  200c = 200c 200c6000 c^2 240c=0 c(c240)=0 c=0 or c=240
