You stopped at Target and bought 3 boxes of cereal and 2 apples for $10. Your friend bought 2 boxes of cereal and 4 apples for $8. Choose the system of equations that represents the situation.

• 3c + 2a = 10

  2c + 4a = 8

• c + a = 18

  3c + 2a = 2c + 4a

• 5c + 6a = 11

  c + a = 18

An organization is selling boxes of brownies for $8 and boxes of chocolates for $9. The number of boxes of chocolates sold was 3 more than twice the number of boxes of brownies sold. The organization collected a total of $417. Choose the system of equations that represents this situation.

• b + c = 417

  b = 3 + 2c

• 8b + 9c = 417

  c = 3 + 2b

• 8b + 9c = 417

  c = 6b
