Identify the SLOPE (m) and the Y-INTERCEPT (b).

To find the y-intercept, find the point where the line crosses the y-axis.

To find the slope, pick two points on the line that are easy to read.
Then see how many units up or down and how many units right or left you need to go from the first point to the second point. Divide the up or down (the rise) by the right or left (the run). That is the slope.

The equation is

y = mx + b,

where m = slope and b = y-intercept.

The ticket price which will maximize the student's council is: C. $3.10.

<h3>What is price?</h3>

Price can be defined as an amount of money which is primarily set by the seller of a product, and it must be paid by a buyer to the seller, so as to enable the acquisition of this product.

Based on the information provided about Valley High School student council, we can logically deduce the following data:

  • Total number of students = 420 students.
  • Lowest ticket price = $2.00.
  • Increase in ticket price = $0.20.
  • Attendance = 20 fewer students

<h3>How to determine the ticket price?</h3>

Mathematically, the equation which model the profit is given by:

Profit = price × number of tickets sold

P(x) = (2 + 0.2x)(420 - 20x)

P(x) = 840 + 84x - 40x - 4x²

P(x) = -4x² + 44x + 840.

For any quadratic equation with a parabolic curve, the axis of symmetry is given by:

Xmax = -b/2a

Xmax = -44/2(-4)

Xmax = -44/-8.

Xmax = 5.5

Ticket price for maximum profit is given by:

Ticket price = 2 + 0.2x

Ticket price = 2 + 0.2(5.5)

Ticket price = $3.10.

John &amp; friends brought 4 bags of popcorn and 3 sodas at the movie for a total of 13.50. At the next movie John &amp; friend
scoray [572]

Answer:

The cost of 5 bags of popcorn and 2 sodas is 14.25 units.

Step-by-step explanation:

We are given the following in the question:

Let x units be the cost of a popcorn bag and y units be cost of soda.

The cost of 4 bags of popcorn and 3 sodas is 13.50.

Thus, we can write the equation:

4x + 3y = 13.50

The cost of 2 bags of popcorn and 5 sodas is 12.00

Thus, we can write the equation:

2x+5y=12

Solving the two equations, we get,

4x + 3y-(4x+10y) = 13.5 - 24\\\Rightarrow -7y  =10.5\\\Rightarrow y = 1.5\\\Rightarrow 2x + 5(1.5) = 12\\\Rightarrow x = 2.25

Thus, the cost of popcorn bag is 2.25 units and the cost of a soda is 1.5 units.

Cost of  5 bags and 2 sodas

==5x+2y\\=5(2.25) + 2(1.5)\\=14.25

Thus, cost of 5 bags of popcorn and 2 sodas is 14.25 units.
