To solve this system of equations, we can use the method of substitution. Let 'a' represent the price per adult ticket, and 's' represent the price per student ticket. By substituting the value of 'a' in terms of 's' into the second equation and solving, we find that the price per adult ticket is $4.64 and the price per student ticket is $2.16.

To solve this system of equations, we can use the method of substitution. Let's assign variables to the unknowns:

Let 'a' represent the price per adult ticket, and 's' represent the price per student ticket.

From the given information, we can set up the following equations:

125a + 65s = 1200

140a + 50s = 1230

We can solve the first equation for 'a' in terms of 's' and substitute it into the second equation:

125a + 65s = 1200 => a = (1200 - 65s) / 125

Substituting the value of 'a' into the second equation:

140((1200 - 65s) / 125) + 50s = 1230

Simplifying the equation gives:

(168000 - 9100s + 2500s) / 125 = 1230

(168000 - 6600s) / 125 = 1230

Multiplying both sides by 125:

168000 - 6600s = 153750

6600s = 14250

s = 2.16

Substituting this value of 's' back into the equation for 'a' gives:

a = (1200 - 65(2.16)) / 125

a = 4.64

Therefore, the price per adult ticket is $4.64 and the price per student ticket is $2.16.
