use guess and check, the answer is:
alan:69 bonnie: 21 and calvin: 63
how did you get the answer
OH, i'm sorry, i switched them around; it is calvin that gets 69, and alan that gets 63
but, here's how i did it
i started with a few guesses, but when i guessed alan having 63, i said okay, he has 3 times as much as bonnie, so i need to divide 69 by 3 and got 21, then it says that calvin gets 6 more than alan so, he has to have 69. to check, you add all of them together and get the total number of marbles of 153, so these numbers are correct.
I hope that explained it for you :-)
got it thank you
