The required cooling capacity in BTUs for an air conditioner is proportional to the area of the room being cooled. A room of 275 square feet requires an air conditioner whose cooling capacity is 5500 BTUs.
a) What is the constant of proportionality? (Round to two decimal places if necessary.)
b) If an air conditioner has a cooling capacity of 13,000 BTUs, how large a room can it cool?
