The drama club is selling tickets to its play. An adult ticket costs $15 and a student ticket costs $11. The auditorium will sea
spin [16.1K]

Answer:

83 adult tickets and 217 student tickets.

Step-by-step explanation:

Let number of adult tickets sold = x

Given that total number of tickets = 300

So, number of student tickets = 300 - x

Cost of adult ticket = $15

Cost of student ticket = $11

Total collection from adult tickets = $15x

Total collection from student tickets =  (300-x)\times 11 = 3300-11x

Given that overall collection = $3630

15x+(3300-11x) = 3630\\\Rightarrow 15x-11x=3630-3300\\\Rightarrow 4x = 330\\\Rightarrow   x = 82.5

So, for atleast $3630 collection, there should be 83 adult tickets and (300-83 = 217 student tickets.

Now , collection = $3632

Britney is solving a quadratic equation. Her first
Liula [17]

Britney used commutative property of addition and distributive property of multiplication  over addition to get to step

The answer is II and IV ⇒ answer 4

Step-by-step explanation:

The quadratic equation is:

3x² - 8 - 10x = 3(2x + 3)

Britney's step is:

3x² - 10 x - 8 = 6x + 9

Lets explain the meaning of:

1. Commutative property of addition is: you can add a and b or b and a

   both give the same answer

2. Distributive property of multiplication over addition is: when the

   number a is multiplied by the sum of two numbers (b + c), the

   first number a can be distributed to both b and c and multiplied

   by each of them separately, then adding the two products ab and

   ac together for the same result as multiplying the first number a by

   the sum (b + c) ⇒ a(b + c) = ab + ac

3. Addition property of equality is: the property that states if you

   add the same number to both sides of an equation, the sides

   remain equal

4. Multiplication property of equality is: The property that states if

   you multiply both sides of an equation by the same number, the

   sides remain equal

Now let us explain Britney's step

∵ She change the places of the terms - 10x and - 8

- She arranges the terms of the left hand side from greatest power

  of x to the numerical term

∴ She used the commutative property of addition

∵ She multiplied 3 by 2x and multiplied 3 by 3

- She multiplied the number out side the bracket by each of the

  two terms in the bracket

∴ She used the distributive property of multiplication over addition

Britney used commutative property of addition and distributive property of multiplication  over addition to get to step

The answer is number 4) II and IV
