The drama club at Del Rosa Middle School is having a production.
Firdavs [7]

Answer:

320 Student Tickets

180 Adult Tickets

Step-by-step explanation:

You can solve this problem by using system of equations. First, we need to figure out our equations.

Equation 1: x as students and y as adults

x+y=500

We get this equation because the total tickets sold was 500. The x represents the students sold to students, and the y represents the tickets sold to adults.

Equation 2:

3x+5y=1850

We get this equation based on the prices. Each student ticket costs $3, and each adult ticket costs $5. The total amount earned was $1850.

Now that we have out equations, we can use system of equations to find our students and adults.

x+y=500

3x+5y=1860

Typically elimination is the easiest strategy because you are able to cross out variables.

3(x+y=500)

3x+5y=1860

Becomes:

3x+3y=1500

3x+5y=1860

We see that both equations now have 3x. We can cancel out 3x.

-2y=-360

y=180

Now that we know y=180, we can plug it back into one of our equations to find x.

x+180=500

x=320

320 student tickets and 180 adult tickets were sold.

A large department store is prepared to buy 3,800 of your tie-dye shower curtains per month for $5 each, but only 3,600 shower c
Ksivusya [100]

Answer:

q= -40p+c

q= -40p+4,000

Step-by-step explanation:

$5 each for 3800 tye-dye shower curtains

$10 each for 3600 tye-dye shower curtains

Slope of the demand line is

3800-3600/5-10

=200/-5

= -40

Demand function is

q= -40p + c

Where c is a constant

For q=3800 and p=$5

Demand function is

q= -40p + c

3800= -40(5)+c

3800= -200+c

c=3800+200

c=4,000

Linear demand function is

q= -40p+4,000

The vertex of this parabola is at (2, -4). When the y-value is -3, the x-value is -3. What is the coefficient of the squared ter
lyudmila [28]

Answer:

The squared term is 1/25

Step-by-step explanation:

The parabola equation in the vertex form is

y = a \times (x - h)^2 + k

where point (h,k) is the vertex and a is the squared term. In this case h = 2 and k = -4. On the other hand, we know that y = -3 and x = -3 are in the parabola. Replacing these values in the formula gives

-3 = a \times (-3 - 2)^2 - 4

Solving for a

-3 + 4 = a \times (-5)^2

1 = a \times 25

a = \frac{1}{25}
