Answer

% owned 4 or more TVs out of those that owned at least 1=$34\%$

Work Step by Step

We know that $114.2$ million US households owned at least one TV set. We are told that $38.4$ million US households owned 4 or more TV sets. To find the percent that owned 4+ TV sets out of the total, we divide: % owned 4 or more TVs out of those that owned at least 1: $\displaystyle \frac{38.4}{114.2}=0.34=34\%$
