let the TOTAL number of the cuffs be X
let the TOTAL number of the COLLARS BE be 30-X
NOW FREDDY COLLECTS 1/2*X + 1/3*(30-X) = X/6 + 10
so charlie would collect 1/2*X + 2/3*(30-X) = -X/6 + 20
by inspection and trial and error we can see that X=12
now putting X=12 in first equation we get 12 and puttin in eqn 2 we get 18
there fore freddy pays 27cents for 12 pieces
so charlie will pay ____ cents for his 18 pieces
THE ANSWER WILL BE 40.5 CENTS

cuff+collar=30
from the data we can assess that cuff is a multiple of 2 so no.of cuffs=12
and collar is multiple of 3 so collar=18
1/2*12cuff+1/3*18collar=27 and 4cuff=3collar solving them we get cost of each. finally the ANSWER is 39CENTS

cuff+collar=30
from the data we can assess that cuff is a multiple of 2 so no.of cuffs=12
and collar is multiple of 3 so collar=18
freddy:
1/2of the collar=6
1/3of the cuffs=6
6t+5/4*6t=27
t=2
then charlie:
6*2+5/4*12*2=42 cents

let the TOTAL number of the cuffs be X

by inspection and trial and error we can see that X=12
now putting X=12 in first equation we get 12 and puttin in eqn 2 we get 18
freddy pay 27 for 6 cuff & 6 collors (4cuff=5colllor i.e. 6 cuff= 7.5 collar)
freddy pay 2 cents for each collor and 2.5 for each cuff
so charli will pay 6*2.5(cuffs)+12*2(collors)=39
