You work in a materials testing lab and your boss tells you to increase the temperature of a sample by 48.7%u2218C . The only thermometer you can find at your workbench reads in degrees Fahrenheit.
PART A) If the initial temperature of the sample is 67.8%u2218F, what is its temperature in degrees Fahrenheit when the desired temperature increase has been achieved?
