Best ResponseYou've already chosen the best response.0hmm.ya 1.8 see 3% of 300=9 3.6% of 300=10.8 so if it has to increase skimmed milk must decrease by 10.89=1.8 pnds

Best ResponseYou've already chosen the best response.3No the answer is 50 lbs If you only remove 1.8 then you are left with 298.2 298.2*.036 = 10.73 which is much higher than 9 since the amount of butterfat remains the same 300(.03) = (300x)(.036) 9 = 10.8 .036x .036x = 1.8 x = 50

Best ResponseYou've already chosen the best response.3thanks another way of looking at it 9/300 = .03 so 9/x = .036 > x=250
