EXAMPLE 3Making a Model for Gas MileageThe gas mileage of a car is the number of miles it can travel on one gallon of gas.(a) Find a formula that models gas mileage in terms of the number of miles drivenand the number of gallons of gasoline used.(b) Henry's car used 10.5 gal to drive 230 mi. Find its gas mileage.12 mi/gal40 mi/gal

Forensics At 8:30 A.M., a coroner went to the home of a person who had died during the night. In order to estimate the time of death, the coroner took the person’s temperature twice. At 9:00 A.M. the temperature was 85.7F, and at 11:00 A.M. the temperature was 82.8F. From these two temperatures, the coroner was able to determine that the time elapsed since death and the body temperature were related by the formula t=10lnT7098.670 where t is the time in hours elapsed since the person died and T is the temperature (in degrees Fahrenheit) of the person’s body. (This formula comes from a general cooling principle called Newton’s Law of Cooling. It uses the assumptions that the person had a normal body temperature of 98.6F at death and that the room temperature was a constant 70F.) Use the formula to estimate the time of death of the person.
