Description:

Jerome has just bought a new heater for his home. He wants to know what the indoor temperature will be after he turns it on for few minutes. He sets the heater to automatically cycle off when it reaches 80 degrees inside. Before the indoor temperature of the house hits 80 degrees, it can be estimated using the equation T = 60 + 2.1m, where T is the indoor temperature of his home in degrees Fahrenheit and m is the number of minutes that have passed since he turned on the heater. What does the constant 60 represent?
