Hi Danielle,
I am going to use g1 for the number of ounces that glass one holds, g2 for the number of ounces that glass 2 holds and so on. I know that
g4 = 10
g7 = 16
The last clue says that "Pouring water twice from glass 4 filled glass 8", in other words
2 g4 = g8 and thus
g8 = 20
The clue before that says "Pouring water twice from glass 3 filled glass 7" and hence
2 g3 = g7 = 16 and hence
g3 = 8
The second clue says "Pouring water from glasses 1 and 3 filled glass 5" and hence
g1 + g3 = g5 which is g1 + 8 = g5
and clue 4 is "Pouring water from glasses 1 and 5 filled glass 7" so
g1 + g5 = g7 = 16 and hence from the equation above g1 + g1 + 8 = 16
What is g1? Can you find the rest now?
Penny
