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:
m = -2
Step-by-step explanation:
5m - 2 = -12
Isolate m.
5m = -12 + 2
5m = -10
m = -10/5
m = -2

Answer: 117
Step-by-step explanation:
Formula for arithmetic sequence is:
= a + (n - 1)d
22nd term = a + (n - 1)d
= a + (22 - 1)d = a + 21d
where, a = 12
d = 17 - 12 = 5.
Therefore, 22nd term will be:
= a + 21d
= 12 + 21(5)
= 12 + 105
= 117
The 22nd term is 117
