Step-by-step explanation:
There is a lot to go over here. Unfortunately it looks like you got a lot incorrect. I'll focus on two problems. Hopefully these examples below will help correct the other mistakes.
---------------------------------------------------------
Problem 7)
We have the starting value be 20 and the ending value be 11. Subtract the values: (end)-(start) = 11 - 20 = -9. The negative indicates we have a drop or decrease.
We'll focus on the positive version of this number, so 9. Divide this value over the starting amount 20 to get 9/20 = 0.45 = 45%
So going from 20 miles to 11 miles is a decrease of 45%
Answer to problem 7 is: 45%
---------------------------------------------------------
Problem 13)
An increase of 300% means we added 3 times the original amount onto the original amount.
We take 300% of 25 to get 3*25 = 75
Which is then added onto 25 to get 25+75 = 100
Answer to problem 13 is: 100
The average rate of change over the interval is 2.17
Explanation:
Given that the cost of a floral bouquet after a discount is given by the function
We need to determine the average rate of change over the interval
The average rate of change can be determined using the formula,
where and
Substituting the value of a and b in the function, we get,
Hence, substituting these values in the formula, we get,
Simplifying, we get,
Dividing, we have,
Thus, the average rate of change over the interval is 2.17
