John had 84 dollars, and his brother Fred owed 12 dollars to his friend. John gave his brother some money. Fred paid his debt an
Alja [10]

Answer:

John have $36 and he should give $48 to his brother for both to have equal money.

Step-by-step explanation:

Given that,

amount of money John have = $84

amount of money John's brother owed to her friend = $12

$12 of the $84 is going to his brother's friend, that leaves $72 for John and his brother.

If they are to finish with the same amount, then each should have half of the John's money after he paid $12

So,

72/2

= 36 each

but since John's brother have to give 12 rupees in debt so

36+12

= $48

So John should have $36 and he should give $48 to his brother.

Help help help help me pleaseeeeeeeee

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.

Please help I can’t figure this out!
Monica [59]

Explanation:

All values in the x-column get filled with -2.

The graph is the vertical line, x = -2.

__

You are told x=-2. There is nothing to figure out. The value of y is irrelevant.

That equation describes a vertical line. The points on the line have x-coordinate -2, and any (every) y-coordinate.
