Quizplus · Accepted Answer

Since there are 4 tires in a set, the total cost of the set is 4 times the cost of one tire. Thus, 
\begin{align*}
4 	imes 	ext{price of one tire} &= \$10.87\
	ext{price of one tire} &= \frac{\$10.87}{4} \
&\approx \$2.72
\end{align*}
The closest answer choice to $2.72$ is $B$ which is $\$67$.
