An outside thermometer reads -5 degrees at 8: 00 a. m. by 12: 30 p. m. the temperature outside has increased by 11 degrees. at 12: 30 p. m. the temperature inside susan's house is is 7 degrees more than 11 times the outside temperature. what was the temperature inside the house then.

73 degrees.

Step-by-step explanation:

So, let's see the information provided in the question.

At 8 AM, the thermometer was reading -5 degrees.

At 12:30 PM, the temperature has increased by 11 degrees, so it's now +6 degrees outside.

Inside Susan's house, the temperature is 7 degrees more than 11 times the outside temperature, at 12:30 PM.

So, we know the outside temperature at 12:30 PM is +6 degrees.

11 times 6 = 66 degrees.

Then we add the additional 7 degrees, to get a total of 73 degrees.
