Given :
When price is $2 dollars he sells 2400 units .
When price is $8 dollars he sells 600 units .
To Find :
If x represents the price of trucks and y the number of items sold, write an equation for the demand curve.
Solution :
Two points are given :


Now , slope is given by :

Now , the equation of line containing these two points and slope -300 is :

Therefore , equation for the demand curve is
.
Hence , this is the required solution .
Answer:
140
Step-by-step explanation:
180 - 40 = 140
X + x+1 + x+2 + x+3 + x+4 = 110
5x +10 = 110
5x = 100
x = 20
The numbers are
20 21 22 23 and 24
Radius equals: 4.51
