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

• 3x + 2y = 315
  2x + 4y = 450
• 3x + 2y = 450
  2x + 4y = 315
• 2x + 2y = 315
  3x + 4y = 450

A large pizza at Papa's Pizzeria costs $6.80 plus $0.90 for each topping.  The cost of a large cheese pizza at Mama's Pizza is $7.30 plus $0.65 fpr each topping.  Which system of equations could be used to determine the number of toppings you need to add to a large cheese pizza from Papa's Pizzeria and Mama's Pizza in order for the pizzas to cost the same?

• p(x) = 7.30 + 0.65x
  m(x) = 6.80 + 0.90x
• p(x) = 6.80x + 0.90
  m(x) = 7.30x + 0.65
• p(x) = 7.30 + 0.90x
  m(x) = 6.80 + 0.65x
• p(x) = 6.80 + 0.90x
  m(x) = 7.30 + 0.65x
