I need help setting up the equation for problem. 110 rail cars make up a train. 75 rail cars are loaded with an average of 11.6% protein per car. What percent protein needs to be loaded on the remaining 35 cars to make the whole 110 car train 12% protein? ** let x=% protein needs to be loaded on 35 cars 11.6%*75+x%*35=12%*110 8.7+35x=13.2 35x=13.2-8.7=4.5 x=4.5/35 x≈.129 or 12.9% % protein needs to be loaded on 35 cars=12.9%
