Given, the cost of 24 tiles $54.50
Step 1: Calculate how much a tile cost. To obtain the cost per tile
[tex]1\text{ tile cost= \$}\frac{54.50}{24}[/tex]Step 2: Calculate the cost to put 36 tiles (i.e the cost per tile multiply by 36)
[tex]\begin{gathered} =\frac{54.50}{24}\times36 \\ =54.50\times1.5 \\ =\text{ \$81.75} \end{gathered}[/tex]Hence, it will cost $81.75 to put 36 tiles
