Each Exterior Angle = (360 degrees) ÷ (Number of Sides)

Number of Sides = 360 degrees / Each Exterior Angle

Number of Sides = 360 degrees / 24

Number of Sides = 15 sides

How do I know?

Farmer Kipp sold 25 horses for a total of $7500 in January and 25 horses for a total of $10500 in February. What is the average

insens350 [35]

Answer:

So Average Price of horse is $360

Step-by-step explanation:

Given:

25 horses sold in January for $ 2500

25 horses sold in February for $10500

TO find:

Average price of horse = ?

Solution:

Average price is usually found out by adding all the values and dividing by its total no of values

Now in our case

Total Horse = 25 + 25

= 50

Total Money = $7500 + $10500

= $18000

Average Price $=\frac{total price}{total horses}$

Average Price $=\frac{18000}{50}$

=$360

So Average Price of horse is $360
