Answer: 5%.
Step-by-step explanation:
Given data:
Old price = $28,640
New price = $27,208
Solution:
Percentage of decrease
= old price - new price / old price * 100
= $28,640 - $27,208 /. $28,640 * 100
= $1432/$28,640*100
= 0.05*100
= 5%.
The percentage of decrease for the car is 5%.

Answer:
f(x) = 
Step-by-step explanation:
Let the equation of the function is,
f(x) = mx + b
Here, m = slope of the line
b = y-intercept
From the graph attached,
y-intercept 'b' = 4
Slope = 
= 
= 
Therefore, equation of the function representing the graph will be,
f(x) =
