Tom, Dick and Mary decided to share expenses for a class party. Tom bought $28
worth of pizza, Dick bought $20 worth of ice cream,and Mary bought $15 worth of
soft drinks. How much should each person pay in order that each of them spends
the same amount of money and how might they accomplish this?
:
How about just adding up the expenses and dividing by 3?
:
Cost per person = = $21
:
Got to thinking perhaps they want to know how much should be exchanged between
them to make sure each pays $21
:
Tom paid $28, so the other two have to pay him
:
Dick gives him 1$, then he's paid $21
Mary give him $6, then she's paid $21
Tom receives $7 so he pays $21

you total up the what was spent 28+20+15=63
:
now you divide that by 3 and that gives you an equal amount that each would pay
:
dollars that each person would pay to be equal. Of course
Mary would have to give Tom $6 bucks and Dick would have to give Tom $1 and that would
end with each paying the $21
