Homer sells tickets for admission to the school play and collects $104. Admission prices are $6 for adults and $4 for children. He sold 21 tickets in total. Write a system to represent this situation.

a = # of adult tickets

c = # of children's tickets.

• a + c = 21

  6a + 4c = 104

• a + c = 104

  6a + 4c = 21

Adult tickets cost $3.00, and student tickets were $1.00. The theatre sold 200 tickets and made a profit of $525. Which system of equations could be used to determine how many student tickets were sold?

s = number of student tickets

a = number of adult tickets

• s + a = 200

  1.00s + 3.00a = $525

• n = d + 2

  .05n + .10d = $525
