Answer:
The number of adults tickets sold = 168.
Step-by-step explanation:
The cost of 1 adult ticket = $10.50
The cost of 1 student ticket = $3.75
The total sales from the ticket = $2071.50
Now, here let us assume
The number of adult tickets sold = a
The number of student tickets sold = b
So, the equation is given as :
10.50 a + 3.75 b = 2071.50
Now, its given the number of students = 82
⇒ <u>b = 82</u>
Putting the value of b in the above equation,w e get:
10.50 a + 3.75 ( 82) = 2071. 50
or, 10.50 a = 2071.50 - 307.5 = 1764
or, a = 1764/10.5 = 168
Hence, the number of adults tickets sold = a = 168.
