There are 50 donkeys and chickens on a farm.  There are a total of 174 legs.  Which system below can be used to figure out how many of each animal the farm has?

• d + c = 174
  4d + 2c = 50
• d + c = 50
  4d + 2c = 174
• d + c = 50
  2d + 4c = 174
• d + c = 174
  2d + 4c = 50

Suppose you have a total of $2.25 in dimes and nickels.  You have twice as many dimes, as nickels.  Which system of equations could be used to determine how many of each you have?

• 0.10d + 0.05n = 2.25
  d = 2n
• 0.05d + 0.10n = 2.25
  d = 2n
• 0.10d + 0.05n = 2.25
  n = 2d
• 0.05d + 0.10n = 2.25
  n = 2d
