A = B - 20 % B = B - 0.2 B = 0.8 B
A = 0.8 B Divide both sides by 0.8
A / 0. 8 = 0.8 B / 0.8
1.25 A = B
B = 1.25 A
B = 2 C Divide both sides by 2
B / 2 = C
C = B / 2
C = 1.25 A / 2
C = 0.625 A = 0.625 A * 100 /100 = 62.5 % A
car A costs 20 percent less than car B. Car B costs twice as much as Car C. The cost of Car C is what percent of the cost of Car A?
How do I set up this question? What should the process of thinking be for these questions?

Thank you! But does this have anything to do with ratios?
