Answer:

  236

Step-by-step explanation:

We assume the cost is a linear function of the number of lessons. That means the slope is the same everywhere.

Let (lessons, cost) = (x, y). We have (4, 84), (8, 160), (12, y3).

  (y2 -y1)/(x2 -x1) = (y3 -y2)/(x3 -x2)

  (160 -84)/(8 -4) = (y3 -160)/(12 -8)

  76 = y3 -160

  y3 = 160 +76 = 236

The cost will be $236 for 12 lessons.

__

The cost function is ...

  y = 19x +8 . . . . for x lessons
