Puzzle : Blueberries and Cups Maria have some blueberries and some cups. If she put 9 blueberries into each cup she will have two cups left. If she put 6 blueberries into each cup she will have three blueberries left over.

Correct Answer: The number of blueberries is equal to number of cups multiplied by 4 minus one left That is : B = 9(C - 2) -> (1) Then the number of blueberries will be equal to the number of cups times three plus one left That is : B = 6C + 3 -> (2) Now substitute the 1st and 2nd equations: B = 9(C - 2) B = 6C + 3 C = 7, B = 45 Therefore Blueberries = 45 and cups = 7
