Mr. Newman bought 8 tickets to a chili supper and spent a total of $30.  He bought a combination of adult tickets for $5 each and child tickets $3 each.  Which system of equations below will determine the number of child tickets, c, and the number of adult tickets, a, he bought?

• 8a + 5c = 30
          a + c = 3
• a + c = 8
       3a + 5c = 30
   
• 5a + 3c = 8
  a + c = 30
• 5a + 3c = 30
        a + c = 8

• 2x +3y ≥ 24
• 2x + 3y < 24
• 2x + 3y > 24

Shameka asked a bank teller for $8.00 in nickels and dimes.  The teller gave her 103 coins.  Which system of equations could be used to find n, the number of nickels, and d, the number of dimes?

• n + d = 8.00
  .05n + .10d = 103
• n + d = 103
  .05n + .10d = 8.00
• n + d = 103
  5n + 10d = 8.00
• n + d = 8
  5n + 10d = 800
