Answer:
I= -20p^2 + 840p
Step-by-step explanation:
When the ticket price is $2 there are 800 passengers daily, but every $0.1 increase in ticket price the number of passengers will be decreased by 2.
You can put information into these equations of:
passenger- = (800-2x)
ticket price= p = $2 + 0.1x
Income is calculated by multiplying the number of the passenger with the ticket price. The answer will be expressed in terms of the ticket price, so we need to remove x from the passenger equation.
p= $2 +0.1x
p-$2 = 0.1x
x= 10p- $20
If p= ticket price, the function for the number of passengers it will be:
passenger = (800-2x)
passenger = 800- 2(10p- $20)
passenger =800- 20p+40
passenger =840- 20p
The function of I will be:
I= passenger x ticket price
I= 840- 20p * p
I= -20p^2 + 840p

Answer:
(0, -8), (1, -11), (-1, -5)
Step-by-step explanation:
It is convenient to solve for y and choose values of x.
y = -3x -8 . . . . . subtract 3x from both sides of the equation
Now, any integer value of x you choose will result in an integer value of y. Often, it is convenient to choose values near zero.
x = -1, y = -3(-1) -8 = 3 -8 = -5 . . . . solution: (-1, -5)
x = 0, y = -3(0) -8 = -8 . . . . solution: (0, -8)
x = 1, y = -3(1) -8 = -11 . . . . solution: (1, -11)
<span> Here are the steps, you fill in the missing parts.
A. The given ratio is:
2 adults per 9 students or the fraction 2/9
Now put that fraction 2/9=x/171 in other words, how many adults (x) for 171 students?
can you cross multiply and get 9x=342
and solve for x?
How you have the number of students and the number of adults.
B. for food multiply $6 times the total number of people.
C. for tickets multiply 4.50 times the student number and
7.50 times the adult number.
D. for the bus parking fee multiply .04 times you total answer in part C.
Now add up the food, tickets, bus parking and I think you have what Mr. Williams has to budget. </span>
There are a few ways to find this. You can use prime factorization to find the LCM or the GCF
The GCF = 77 so 77 will divide into 539 and 3465
Answer = 77
