A theater is selling tickets for a performance. Mr. Smith purchased 8 senior tickets and 5 child tickets for $136 for his friend
ICE Princess25 [194]

Answer:

The price of a senior ticket is $12.

Step-by-step explanation:

Given:

Mr. Smith purchased 8 senior tickets and 5 child tickets for $136. Mr. Jackson purchased 4 senior tickets and 6 child tickets for $96.

Now, to get what is the price of a senior ticket.

Let the senior ticket be x and the child ticket be y:

So, according to question

8x+5y=136.........(1)

4x+6y=96...........(2)

Now, we have system of equations:

Multiplying the equation (2) by -2 we get:

-8x-12y=-192.......(3)

Now, adding the equation (3) and (1) the variables and the numbers:

-8x-12y+8x+5y=-192+136

-7y=-56

Dividing both sides by -7 we get:

y=8

Putting the value of y in equation (2) we get:

4x+6(8)=96

4x+48=96

On solving the equation we get:

x=12.

Therefore, the price of a senior ticket is $12.
