Thanks for responding so fast. First, Oberon is in the state
of Colorado and we got our answer by using the clues to make
equations. The equations we made were...
Chelsea is less than 4 times Aslan
Bengt is greater than 120
Then we guessed on a weight for Bengt. We knew he was greater
then 120 so we started small and began with 121 lbs. We, then,
plugged in the number into our equations and solved each equation
one-by-one using the information from the previous equation. This
didn't work because when we plugged the numbers in, the equations
didn't solve correctly. Although, we figured the answer couldn't be
too far off. It definently wasn't 122lbs. so we plugged in 121.5 and
solved for the rest of the animals' weights. This number agreed with
all of the equations.
And, to answer your third question, my group and I don't know
any other answers to this problem but, we're sure that there
