Answer:
This looks like a question on thermometers and how to read temperature using various thermometric properties.
x / [p(x) - p(0)] = 100 / [p(100) - p(0)]
x is the temperature you want to calculate. p(x) is the thermometric property at x Kelvin.
x / [5.5 - 4] = 100 / [5 - 4]
x = 150C
Extra: your teacher probably neglected that the pressure and volume of a gas is zero at absolute zero, zero Kelvin, -273C. According to the question, the gas will reach zero pressure at -400C.
