A scientist needs 10 litters of 20% acid solution for an experiment, but she has only a 5% solution and a 40% solution. To the nearest tenth of a liter, about how many liters of the 5% and the 40% solutions should she mix to get the solution she needs?
Part A
A. (0.20)(10)=0.05x+0.40x
B.(0.20)(10)=0.05x+0.40(10-x)
C.(0.20)(10)=0.05(10)+0.40(10-x)
D.(0.20)(10)=0.05(10-x)+0.40(10-x)< br />
Part B
