Answer:
160 tiles.
Step-by-step explanation:
First let's make an equation.
Each tile costs $4, let's make <em>t=number of tiles.</em>
+$15.82, and the total cost being $655.82
So ideally our equation would look like
<em>4t+15.82=655.82</em>
<em />
Now solve.
First, subtract <em>15.82 </em>on both sides.
<em>4t=640</em>
Second, divide <em>4 </em>on both sides to make the variable <em>t </em>by itself.
<em>t=160</em>
<em />
So, the contractor purchased 160 tiles.
