The Maplewood Symphony Orchestra sold 146 tickets and collected a total of $1036 in ticket sales. Admission was $5 for children and $8 for adults. Write two equations that would be used to solve the system.

• 
  c+a=1036

  8c+5a=146

• 
  c-a=146

  8c+5a=1036

• 
  c+a=146

  5c+8a=1036

• 
  c+a=146

  5c-8a=1026
