• 4x + 6y = 3
  13.5x - 13y = 6
• x + y = 4
  x - y = 6
• 4x + 6y = 13
  3x + 7y = 13.5
• 4x - 6y = 13
  3x - 7y = 13.5

The talent show committee sold a total of 530 tickets in advance. Student tickets cost $3 each and the adult tickets cost $4 each. If the total receipts were $1740, which system could be used to find how many of each type of ticket were sold?

• S + A = 530
  3S + 4A = 1740
• S + A = 530
  4S + 3A = 1740
• S + A = 1740
  3S + 4A = 530
• S + A = 1740
  4S + 3A = 530

An MLB stadium sells three types of tickets. Reserved tickets are sold for $20 each, field level tickets are sold for $50 each, and box seat tickets are sold for $100 each. You purchase 10 total tickets for $370. You have twice as many reserved tickets as field level tickets. Set up the system using the variables

x: reserved

y: field-level

z: box seats

• $x+y+z=370$
  $20x+50y+z=100$
  $2x=y$
  

• 
  

  $x+y+z=10$
  $20x+50y+100z=370$
  $x=2y$
  

• $2x+y+z=370$
  $20x+50y+100z=2$
  $2z=x$

A local grocery store makes a 9-pound mixture of trail mix. The trail mix contains raisins, sunflower seeds, and chocolate-covered peanuts. The raisins costs $2 per pound, sunflower seeds cost $1 per pound, and chocolate-covered peanuts cost $1.50 per pound. The total cost for the mixture is $14.50. Set up the system of equations using the following:

x: raisins
y: sunflower seeds
z: chocolate-covered peanuts

•  $x+y+z=\text{14}.50$  
   $2x+y+1.50z=9$  
   $x=2y$  
  

•  $x+y+1.5z=9$  
   $2x+y+z=14.50$  
   $2x=y$  
  

• 
  

   $x+y+z=9$  
  

   $2x+y+1.50z=14.50$  
   $x=2y$
