Raul is performing an experiment. He pours water into a glass and measures the temperature of the water at 72.3°F. Then he adds a few ice cubes to the glass of water. He measures the temperature of the water again and finds that it has changed by -39.1°F. Complete the steps below to learn more about the temperature change of the water.

Part A
Write an expression that represents the temperature (in degrees Fahrenheit) of the water after Raul added the ice cubes. Write the expression as the sum of two numbers.

Part B
Rewrite the expression in part A by breaking up each of the place values. In this case, the place values are tens, ones, and tenths.

Part C
Next, rearrange the expression in part B using the Commutative Property so the terms with the same place value are next to each other.

Part D
Now group the terms in the expression in part C using the Associative Property.

Part E
Simplify the expression in part D to find the temperature of the water after Raul added the ice cubes. Show your work.

Part F
Several minutes later, Raul decides to measure the water temperature again. He finds that the temperature changed by -0.6°F. What is the temperature of the water now? Show your work.
