The temperature on a summer afternoon is 85 degrees fahrenheit. define a variable and write an expression to find the temperature after it changes. then evaluate your expression for a decrease of degrees fahrenheit

 b.) Any temperature change is the original temperature plus the numerical value of the change. (temp + change) If it is an increase, the number will be positive. If it is a decrease, the number will be negative. 

Since there is a decrease of 11, c would be replaced with -11. When you plug this into your expression (85 + c: 85 + -11), the answer to this would be 74.
