L = B + 105
H = L + 24.....H = B + 105 + 24 ...H = B + 129
H + L + B = 324
(B + 129) + (B + 105) + B = 324
3B + 234 = 324
3B = 324 - 234
3B = 90
B = 90/3
B = 30 <==Bart's marbles
L = B + 105
L = 30 + 105
L = 135 <=== Lisa's marbles
H = B + 129
H = 30 + 129
H = 159 <=== Homer's marbles
-7 feet because 0 is water level and the deck of the ship is 7 feet above eatet and the cabin is 14 feet below the deck so you subtract 14 from 7 and get -7 (7-14=-7)
