reverend James insists that every person attending Easter services make a cash donation to the charity box. there are three choices a small donation of $1 a moderate donation or large donation the. large donation is 4 times as much as the moderate donation if 120 people attend Easter Service and 50% make a large donation 20% make a small donation and the rest of the people make a moderate donation $4,440 will be collected. how much money is a moderate donation?

Respuesta :

120 people.  50% is 60 people.  20% is 24 people, the rest is 36.
Let L=large donation, M=medium.  We also have L=4M.  The donation equation is then:
60L+36M+24=4440
60L+36M=4416  substitute L=4M
276M=4416
M=4416/276=16
So the answer is $16
