`input()` reads data entered by the user. The result of `input()` is initially a string. `float()` converts a numeric string into a number that may contain a decimal part. The `+` operator adds numbers. The `*` operator multiplies numbers. The `/` operator performs regular division and may return a decimal number. `print()` displays the program result. Print only what the problem statement requires.

**Connection to this task.** The `/` operator performs true division and returns a floating-point value in Python. This matters for averages, percentages, and formulas whose result may be fractional. The expression `c * 9 / 5 + 32` shows how this idea is applied to the task data.
