**Answer:**

**P=3T-50**

**Step-by-step explanation:**

Form the given four values we can assume a **linear relationship** between profit and the no of tickets sold.

Let the equation corresponding to that be some P=aT+b.

Now substitute the first set of values(100,50) in the above equation we get

100=50a+b.

Now substituting second set of values (100,250) we get 250=100a+b.

Let these equations be eq1 and eq2.

Now substract eq1 from eq2 we get **50a=150 or a=3.**

**Substitite value of a in one of the equations we get b=-50.**

**∴P=3T-50**
