Answer
Average rate of change per day from Monday to Friday = 2.5 degrees per day
Explanation
The average rate of change of any quantity with respect to time (per day) is given as
[tex]\text{Average rate of change = }\frac{(New\text{ value) - (}Old\text{ value)}}{Number\text{ of days}}[/tex]For this question,
New value = Temperature on Friday = 86 degrees
Old value = Temperature on Monday = 76 degrees
Number of days from Monday to Friday = 4 days
[tex]\begin{gathered} \text{Average rate of change = }\frac{(New\text{ value) - (}Old\text{ value)}}{Number\text{ of days}} \\ \text{Average rate of change = }\frac{86-76}{4} \\ =\frac{10}{4} \\ =2.5\text{ degr}ees\text{ per day} \end{gathered}[/tex]Hope this Helps!!!
