Answer 1

Explanation

Given: Leila purchased 21,5cm of wire for $17.20.

Required: To determine the unit price in dollars per centimeter.

This is achieved thus:

To determine the unit price per centimeter, we divide the cost by the length of wire as follows:

$\begin{gathered} 21.5cm=\text{ \ }17.20 \\ \therefore1cm=\frac{\text{ \ }17.20}{21.5}=\text{ \ }0.80 \end{gathered}$

Hence, the answer is:

$\text{ \ }0.80\text{ }per\text{ }centimeter$
