Answer
$\approx \$4.00$ per pair
Work Step by Step
We see that 6 pairs of tights cost $\$23.98$. To find out how much one pair would cost, we divide:
$~~~~~~3.996$
$6\overline{)23.980}$
$~~~~\underline{18}$
$~~~~~~~59$
$~~~~~~~\underline{54}$
$~~~~~~~~~~58$
$~~~~~~~~~~\underline{54}$
$~~~~~~~~~~~~40$
$~~~~~~~~~~~~\underline{36}$
$~~~~~~~~~~~~~~4$
We can stop the division with the remainder of 4 because we only need to round to the nearest cent ($\$0.01$):
$3.996\approx \$4.00$
