Cathy had --- x
Ben had --- x-60
Abel had ---- 296
Danny had --- x/5
total number = 11x/5 + 236
x-60 = .35(11x/5+236)
times 100
100x - 6000 = 77x + 8260
..
x = 620
So Ben had 620-60 or Ben had 560 stamps
check:
Cathy had 620
Ben had 560
Abel had 296
Danny had 124
total = 1600
What is 35% of that? 560 , which is what Ben had
my answer is correct
Why so many stamps ?????
Abel, Ben, Cathy and Danny had some stamps. Abel had 296 stamps and Ben had 60 stamps less than Cathy. Ben had 35% of the total number of stamps and Danny had 1/5 of the number of stamps Cathy had. How many stamps did Ben have?

A = 296
B = C-60 = 0.35 T
D = 0.2 C
and A + B + C + D = T
so then B + C + D = T- 296
B + (B + 60) + 0.2 ( B + 60) = B / 0.35
2.2 B + 72 = 2.86 B
0.657 B = 72
B = 110
