The theater arts students sold 500 tickets to the spring musical and collected a total of $3,160. Adult  tickets sold for $8.00 and student tickets sold for $5.00. Which system of equations is used to find a ,  the number of adult tickets and s , the number of student tickets sold?

• a + s = 3160

       5a + 8s = 500

• a + s = 3160

       8a + 5s = 500

• a + s = 500

  5a + 8s = 3160

• a + s = 500

  8a + 5s = 3160

After graduation, Duke’s grandfather spent $158.81 taking the entire family out to eat at a buffet.  Adults ate for $8.99 and children ate for $6.99. The number of adults was one more than twice the  number of children. Which system of equations is used to find a , the number of adults, and c , the  number of children in Duke’s family?

• 8.99a + 6.99c = 158.81

  a = 2c + 1

• 6.99a + 8.99c = 158.81

  c= 2a + 1

• 8.99a + 6.99c = 318.62

  c= 2a + 1

• 8.99a − 6.99c = 158.81

  a = 2c + 1

Robert has $60 in his savings account and he deposits $30 each week. The graph shows the amount of  money his sister Deanna has in her savings account.

Which system of equations is used to find x , the number of weeks it will take for them to have the  same amount, y , in their savings accounts?

• y = 60x + 30

  y = 20x + 40

• y = 60x +30

  y = 20 + 40x

• y = 60 + 30x

  y = 20x + 40

• y = 60 + 30x

  y = 20 + 40x
