coupons to Bill and 1/6 of his charity coupons to Carl. After that, all 3 boys 

had the same number of charity coupons.

 

(a)  Who had more charity coupons at first. Bill or Carl?

 

(b)  Based on your answer in (a), how many more charity coupons did the 

      boy have at first?

A  +  B  +  C==528.....................................(1)

 

A   -  3/8A  - 1/6A ==11/24A left

 

11/24A ==B + 3/8A...................................(2)

 

B  +  3/8A == C  +  1/6A............................(3), solve for A, B, C

 

A==384   and   B==32   and   C==112  - what the 3 boys started with.

 

a) Carl had 120 vs Bill who had 32

 

b)  See above
