At 0°c, the volume of a gas is 22 liters. for each degree the temperature t (in degrees celsius) increases, the volume v (in liters) of the gas increases by 225 . write an equation that represents the volume of the gas in terms of the temperature.

I believe there is a typo here. Using ideal gas equation, the increases for every degree would be 22L/273= 0.08L= 2/25 liter.
So, it seems the number 225 means 2/25.

Since every degree(T) means an increase of 2/25L in volume, the equation would be
V(in liters)= 22 + 2/25 T

7p=14 so then you would divide by p=2
