Given:
The graph shows the relationship between the number of pounds of apples purchased and the total cost of the apples.
To find:
The cost of 1 pound of apples.
Solution:
We need to find the slope of the line to get the cost of 1 pound of apples.
From the given graph it is clear that the line passes through two points (0,0) and (2,3). So, the slope of the line is
Therefore, the cost of 1 pound of apples is $1.5.
6v+4w-4
Because you do -*-6v=positive 6v then -*-4w=positive 4w and then -*4=-4 and that takes care of the parenthesis
Basically you multiply the outside number or sign by all things inside the parenthesis
So in this problem you multiplied the negative sign by all the things inside the parenthesis
Four hundred sixty-five thousand one hundred
Answer:
At Maximum point;
x(max) = 50
p(max) = $100
Maximum revenue = $5,000
Step-by-step explanation:
The price function is;
p(x) = 200 − 2x
where
p is the price (in dollars) at which exactly x trucks will be rented per day.
The revenue function R(x) can be written as;
R(x) = p(x) × x
Substituting p(x) equation;
R(x) = (200-2x)x
R(x) = 200x-2x^2 ........1
To maximize R(x), at maximum point dR/dx = 0
differentiating equation 1;
dR/dx = 200 - 4x = 0
4x = 200
x = 200/4
x = 50
Substituting x = 50 into p(x)
p(50) = 200 - 2(50) = $100
p = $100
Maximum revenue is;
R = p × x = $100×50
R = $5,000
