Let there be $$100$$ people who were eligible to vote

people between 18 & 21 who were eligible to vote $$= 100*8$$%$$=8$$

people between 18 & 21 who voted $$= 8*85$$% $$= 8*0.85$$

Therefore % people between 18 and 21 who actually voted were what percent of those people eligible to vote $$= 8*\frac{0.85}{100}*100 = 6.8$$

Option C

I think the answer should be (C) i.e 6.8 as 85% of 8 is 6.8.

This question can be solved using multipliers only.

(.08)(.85) = .068 * 100 = 6.8%

Call those "eligible to vote who were between the ages of 18 and 21," Z

Z = .08 of all eligible voters

"85% of those eligible to vote who were between 18 and 21 Z actually voted."

Z = .08
85 percent = .85
.85 of .08 =
(.85 * .08) = .068 * 100 = 6.8%
