19. The temperature on a summer afternoon is 85°F
The temperature on a summer afternoon is 85°F. Define a variable and write an expression to find the temperature after it changes. Then evaluate your expression for a decrease of 11 degrees Fahrenheit.
11 + c; 11 + (–85) = 96
85 + c; 85 + (–11) = 74
11 – c; 11 – (–85) = 74
