A new temperature scale was invented by a scientist named Pat and is called the Patrius scale. On her scale, water froze at 35°P and boiled at 280°P. What Celsius temperature is equal to 150° P? (Give answer to two significant figures) pleas show work and explain by detail steps, because i have the answer but i don't know how to get to it
