Units sold: x
Profit for corresponding units sold:  y

Given:
x₁ = 80 (units)        x₂ = 110 (units)
y₁ = 80 (profit)        y₂ = 140 (profit)

Step 1:  Find the Linear Equation,  using the Two-Point Form equation:

                y₂ - y₁
y - y₁ =  -------------   (x - x₁)      
                x₂ - x₁

 
                140 - 80
y - 80 =  ---------------  (x - 80)
                110 - 80   


                60
y - 80 =  ------  ( x - 80)
                30

y - 80 = 2 (x - 80)

y = 2x - 180 + 80

y = 2x - 80  ⇒   Linear Function

Step 2:  Find the average profit (y)  for 250 (x)  units sold?

     y = 2x - 80

     y = 2(250) - 80
  
     y = 500 - 80

     y = 420

ANSWER:  If the company sells 250 units, the profit is Php 420.
