the number of adult tickets that were sold is 321

the number of adult tickets that were sold is 227

Step-by-step explanation:

Let x represent the number of adult tickets that were sold.

Let y represent the number of adult tickets that were sold.

Regal theater in Tikahtnu sold 548 tickets to Moana on Sunday. This means that

x + y = 548

A adult's ticket was $6.50 while a child's ticket was $3.50. In total, they took in $2881 in sales of these ticket. This means that

6.5x + 3.5y = 2881 - - - - - - - - -1

Substituting x = 548 - y into equation 1, it becomes

6.5(548 - y) + 3.5y = 2881

3562 - 6.5y + 3.5y = 2881

- 6.5y + 3.5y = 2881 - 3562

- 3y = - 681

y = - 681/-3 = 227

Substituting y = 227 into x = 548 - y, it becomes

x = 548 - 227 = 321

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
