Question 229645
"Five housemates held a party. They agreed to share the expenses equally.
 Leroy spent $20 on soft drinks. Alex spent $5 on paper plates. 
Kulwinder spent $13 on decorations. Max spent $16 on snacks.
 Bobbi spent $8 on envelopes and paper to send out invitations, and she also spent $7.40 on postage stamps.
 Who owes money to whom?" 
:
Wouldn't you just find out total money that was spent. Divide that by 5.
That's the share of each person. Compare that with the amt each spent.
:
Let s = amt each owes to the total
s = {{{(20 + 5 + 13 + 16 + 8 + 7.40)/5}}}
s = {{{69.40/5}}}
s = $13.88 amt each should pay
:
Then I assume these would be the sub problems:
L: 20 - 13.88 = 6.12 owed to Larry
A: 13.88 - 5 = 8.88 has to be paid by Alex
K: 13.88 - 13 = .88 has to be paid by Kul
M: 16 - 13.88 = 2.12 owed to Max
B: 8 + 7.40 - 13.88 =  1.52 owed to Bobbi
:
One way is have everyone who owes, put the money on the table, that would be
8.88 + .88 = 9.76
Then each remove what is owed them, should equal above amt if we did this right
L takes: 6.12
M takes: 2.12
B takes: 1.52
--------------
total $  9.76

How about this? Did this make sense?
