Solving System of Equations Applications

A movie theater sells adult tickets for $10 each and child tickets for $6 each. If a total of 100 tickets were sold for $800, write a system of equations to represent this scenario and solve for the number of adult and child tickets sold.

• The number of adult tickets sold is 60, and the number of child tickets sold is 40.

• The number of adult tickets sold is 80, and the number of child tickets sold is 20.

• The number of adult tickets sold is 50, and the number of child tickets sold is 50.

• The number of adult tickets sold is 70, and the number of child tickets sold is 30.
