Answer:
p = 70n -1500
Step-by-step explanation:
The slope-intercept form of the equation is ...
p = 70n +b
We know that p = -800 for n = 10, so we can find b:
-800 = 70·10 +b
-800 -700 = b = -1500
The net profit equation is ...
p = 70n -1500
The rest station is the midpoint of the given coordinates:
(-20+35)/2 , for the x value and (15+-12)/2 for the y value.
Coordinates of the rest station: (7.5, 1.5)
How far is the destination? Use the distance formula : D² = √(x1-x2) + (y1-y2)
(-55)² + (27)² = D² D = √3754 = 61.27

Answer:
$599
Step-by-step explanation:
Given: Discount- 40% off on original price.
