Please help me i need this before Wednesday , will mark brainiliest and I don’t know how to solve it

The price of one adult ticket is $11 and the price of one student ticket is $6.

Step-by-step explanation:

We can write a system of equations to represent the situation. Let a represent the price of adult tickets sold and s represent the price of student tickets.

On the first day, nine adult tickets and 12 student tickets were sold for a total of $171. Hence:

And on the second day, 13 adult tickets and 14 student tickets were sold for a total of $227. Hence:

This yields a system of equations:

We can solve using elimination. Note that the LCM of 12 and 14 is 84. Hence, we can multiply the first equation by -7 and the second by 6:

Adding the two equations together now produces:

Therefore, the price of one adult ticket is $11.

To find the price of one student ticket, use either one of the original equations:

In conclusion, the price of one adult ticket is $11 and the price of one student ticket is $6.
