Answer 3

first review the other post

Answer 4

try to do the same with this
post so I can see your work

Answer 5

ok give me a few minutes:)

Answer 6

to do the average after you get the total divide by the number of entries you had to add

for this problem you had 5 entries

Answer 7

so this is what I got so far and got a little stuck:

(15*16)+20=260+20=280 ounces

(20*16)+15=335+15=350 ounces
so 280+350=630
630/16=39.375
so now im stuck on where to go now

Answer 8

that's what jack told you to do

I prefer if you do it the easier and normal way.
I am sure you will not get stuck

Answer 9

continue what you had started. like in my example add all the ozs together
take out groups of 16 because 16 ozs make 1 lb any remainder stays as ozs
next all all the lbs including the ones you converted from groups of 16 ozs.
