To find the linear equation:

1. Identify two given points: (10, 110) and (15, 135).
2. Calculate the slope:
m = \frac{135 - 110}{15 - 10} = \frac{25}{5} = 5
3. Use the point-slope form with point (10, 110):
y - 110 = 5(x - 10)
4. Solve for \( y \):
y - 110 = 5x - 50
y = 5x + 60
5. Use the equation \( y = 5x + 60 \) to find the cost for 90 units:
y = 5(90) + 60 = 450 + 60 = 510

Answer:
y = 510
