Answer:
The inequality that represents the age of the group, "x", is: 
Step-by-step explanation:
To express this problem in an inequality we will attribute the age of the members on the group with the variable "x". There are two available information about "x", the first states that every member of the group is older than 17 years, therefore we can create a inequality based on that:

While the second data from the problem states that none of than is older than 54 years old, this implies that they can be at most that old, therefore the inequality that represents this is:

In order for both to be valid at the same time x must be greater than 17 and less or equal to 54, therefore we finally have:

...more information is clearly needed
(y-y1) = m(x-x1)
y-2 = 5(x-6)
Therefore, point (x1,y1) lies on the line of equation
Therefore, point (6,2) lies on the line with the point slope equation y-2=5(x-6)
2c+3d=900
C=x
D=350-x
2x+3 (350-x)=900
Solve for x to get number of children
attended the fair that day
2x+1050-3x=900
2x-3x=900-1050
-1 x=-150
x=150 children
350-150=200 adult
(a) The profit when the company sold 1000 pens is -1000.
(b) The number of pens that are required to sell in the break-even is 1167.
(a)
The profit when the company sold 1000 pens is
P = R - C
= 9x - (3x + 7000)
= (9 × 1000) - (3 × 1000 + 7000)
= 9000 - (3000 + 7000)
= 9000 - 10000
= -1000
(b)
The number of pens that are required to sell in the break-even is
R = C
9x = 3x + 7000
9x - 3x = 7000
6x = 7000
x = 1167
Therefore we can conclude that:
(a) The profit when the company sold 1000 pens is -1000.
(b) The number of pens that are required to sell in the break-even is 1167.
