Question

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.
76 – c; 76 – (–8) = 84; 84°F


8 – c; 8 – (–76) = 68; 68°F


76 + c; 76 + (–8) = 68; 68°F


8 + c; 8 + (–76) = 84; 84°F

Answer 1

The third choice is the correct answer because c is subtracted when negative and 76 is the starting value
