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) = 74; 74°f 85 – c; 85 – (–11) = 96; 96°f 85 + c; 85 + (–11) = 74; 74°f 11 + c; 11 + (–85) = 96; 96°f

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.
