The school that Stefan goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 3 senior citizen tickets and 1 child ticket for a total of $38. The school took in $52 on the second day by selling 3 senior citizen tickets and 2 child tickets. Which equations represents the system that could be used? 

• 1s + 3c = 38
  2s + 3c = 52
• 3s + 1c = 38
  3s + 2c = 52
• s + c = 38
  s + c = 52
• 3s + 3c = 38
  1s + 2c = 52

A large one-topping pizza costs $8.99. Additional toppings are $0.49 each. How much would a pizza cost, c, if there are t additional toppings?

• c = 0.49t + 8.99
• c = 0.49t - 8.99
• c = -0.49 + 8.99
• c = -0.49 - 8.99
