The temperature on a summer afternoon is 76°F. Define a variable and write an expression to find the temperature after it changes. Then evaluate your expression for a decrease of 8 degrees Fahrenheit.

A. 8 – c; 8 – (–76) = 68; 68°F

B. 76 – c; 76 – (–8) = 84; 84°F

C. 76 + c; 76 + (–8) = 68; 68°F

Letting "c" be the value of the temperature change, looking at the choices, the nearest answer would be C. " 76 + c; 76 + (–8) = 68; 68°F ".

76 is the base or current temperature, then c would be the change in temperature experience. Since a decrease of 8 degrees is to be experienced, it is denoted by the negative symbol on 8.
