Each additional hour or rental costs $25.

Step-by-step explanation:

Given equation is;

4h+150=250 Eqn 1

Where 150 is the cost for first 2 hours and 4h is the cost for remaining hours.

Total cost = $250

Solving Eqn 1

Subtracting 150 from both sides

$4h+150-150=250-150\\4h=100$

Dividing both sides by 4

$\frac{4h}{4}=\frac{100}{4}\\h=25$

Each additional hour or rental costs $25.
