Let c be the number of stickers that Carlos has.
c + c + 40 + 2c + 40 = 300
4c = 220
c = 55
c + c + 40 + 2c + 40 = 300
4c = 220
c = 55

That's not right. c does not equal 55.
Peter - 2 x c
Ali - Has c + another 40
Carlos - c
(2c) + (c + 40) + (c)
= 4c + 40 = 300
= 4c = 300-40
= 4c = 260
= 4c / 4 = 260 / 4
= 0 = 65
c = 65
Feel free to correct me if I'm wrong.
