Ms. Cai’s class is studying a tile pattern. The rule for the tile pattern is $y=10x-18$. Kalil thinks that Figure 12 of this pattern will have $108$ tiles. Is he correct? Justify your answer.  

• Hint:

  $y=$ # of tiles
  $x=$ Figure #

  More Help:

  Substitute the information from the problem into the equation $y=10x-18$.

  Answer:

  $102$ tiles. Kalil is wrong.
