We have been given that the cost of admission is $48 for four pets and $96 for eight pets. We are asked to determine the independent variable and the dependent variable in the given linear relationship.
We can see that as the number of pets is increasing cost of admission is also increasing. This means that cost depends on number of pets.
Therefore, cost of admission is dependent variable and number of pets is independent variable.
To find rate of change, we will use slope formula.
We have been given two points on line that are (4,48) and (8,96).
Upon substituting the coordinates of our given points in slope formula, we will get:
Therefore, the rate of change is $12 per pet.

Answer:
(1 ) Inner curved surface area of the well is 109.9 sq. meters.
(2) The cost of plastering the total curved surface area is 4396.
Step-by-step explanation:
The inner diameter = 3.5 m
Depth of the well = 10 m
Now, Diameter = 2 x Radius
⇒R = D/ 2 = 3.5/2 = 1.75
or, the inner radius of the well = 1.75 m
CURVED SURFACE AREA of cylinder = 2πr h
⇒The inner curved surface area = 2πr h = 2 ( 3.14) (1.75)(10)
= 109 sq. meters
Hence, the inner curved surface area of the well is 109.9 sq. meters.
Now, the cost of plastering the curved area is 40 per sq meters
So, the cost of total plastering total area = 109.9 x(Cost per meter sq.)
= 109.9 x (40)
= 4396
Hence, the cost of plastering the total curved surface area is 4396.
