Ann and Betty together have $60. Ann has $9 more than twice Betty’s amount. How much money does each have?

• A + B = 60
  2A + B = 9

• A + B = 60
  A + 2B =  9

• A + B = 60
  A = 9b 

• A + B = 60
  A = 2b + 9

On Monday Joe bought 10 cups of coffee and 5 doughnuts for his office at the cost of $16.50.  It turns out that the doughnuts were more popular than the coffee.  On Tuesday he bought 5 cups of coffee and 10 doughnuts for a total of $14.25.  Which equations could be used to determine the cost of the coffee? 

• 10c + 5d = 14.25
  5c + 10d = 16.50

• 10c + 5d = 16.50
  5c + 10d = 14.25

• c + d = 10
  5c + 10d = 16.50

• c + d = 5
  5c + 10d = 16.50
