Roman mixes 12 liters of 8% acid solution with a 20% acid solution, which results in a 16% acid solution. find the number of liters of 20% acid solution in the new mixture. construct a table to organize the information, and show all of your work to solve the problem

(12(0.08)+x(0.2))/(12+x)=0.16  perform indicated multiplication on left side

(0.96+0.2x)/(12+x)=0.16  multiply both sides by (12+x)

0.96+0.2x=1.92+0.16x  subtract 0.16x from both sides

0.96+0.04x=1.92  subtract 0.96 from both sides

0.04x=0.96  divide both sides by 0.04

x=24

So 24 liters of 20% acid solution is in the new mixture.

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
