Answer:

168 adult adult ticket were sold

Step-by-step explanation:

Hello

The tickets cost for adults is     $10.50

The tickets cost for students is $3.75

number of adult ticket sold:       A

number of student  ticket sold:  B

10.50A+3.75B=2071.50     Equation 1

B=82                                   Equation 2

replacing equation 2 in equation 1

10.50A+3.75(82)=2071.50

10.50A=2071.50-307.50

[tex]A=\frac{1764}{10.50} \\\\A=168\\\\\\[/tex]

168 adult adult ticket were sold
