Tickets to a 3D movie cost $12.50 for adults and $8.50 for children. The theater can seat up to 180 people. A total of $1826 was
Serggg [28]

Let, number of children are x and number of adult are y.

Total number of seats, T = 180.

x + y = 180     ....1)

Tickets to a 3D movie cost $12.50 for adults and $8.50 for children.

So, total amount :

8.5x + 12.5y = A

8.5x + 12.5y = 1826    ....2)

Solving equation 1) and 2) , we get :

8.5x + 12.5( 180 - x ) = 1826

8.5x - 12.5x + 2250 = 1826

-4x = -424

x = 106

y = 180 - 106 = 74

Therefore, the number of adult tickets and the number of children's tickets that were sold are 74 and 106.

Hence, this is the required solution.

The system of equations x + 2y = 6 and x – 4y = 0 is graphed below. What is the solution to the system of equations?
blagie [28]

Step-by-step explanation:

x + 2y = 6....(1) \\  \\  x - 4y = 0\\ \implies \: x = 4y....(2)\\  \\ from \: equations \: (1) \: and \: (2) \\ 4y + 2y = 6 \\   \therefore \: 6y = 6 \\  \\ \therefore \: y =  \frac{6}{6}  \\  \\  \huge \red{ \boxed{ \therefore \: y =  1}} \\  \\ substituting \: y = 1 \: in \: equation \: (2) \\  \\ x = 4y \\  \\ \therefore \: x = 4 \times 1 \\  \\  \huge \orange{ \boxed{\therefore \: x = 4 }} \\  \\ \therefore \: (x, \:  \: y) = (4, \:  \: 1) \\ is \: the \: required \: solution. \\
