A bag of frozen vegetables with temperature 32◦F is placed in a 75◦F room. After 20 minutes, the temperature of the vegetables has risen to 41◦F. Using this information, find an exponential formula for the temperature of the vegetables where time is measured in minutes. To find the exponential formula, transform the temperature into a new variable for which the problem can be solved as an exponential growth/decay problem. Then find the formula in that variable and transform back to temperature. Based on the formula, what is the temperature of the vegetables after 45 minutes?

In one of the videos I said that a typical American household uses energy at a rate of about 10,000 joules per second. A shorthand unit for this would be "10 kilowatts". Using energy at this rate costs about $1.50 per hour (this is not quite right, as it assumes that all the energy is electrical energy, which is relatively cheap, but let's go with this for an estimate). How much does this energy usage cost for a year?
