In a box, (5/8 ) of the beads were red, (1/3) of the remaining beads were green and the rest were blue. After (5/6) of the blue beads and 5 green beads were used, 128 were left. How many beads were there in the box at first? My work: I couldn't get far, but this is what I got. Red = r Green = g Blue = b (5/8 )r + (1/8 )(g  5) + (2/8 )(b  5/6) = Total  128

t = total beads r = 5t/8 g = (t  5t/8)/3 = t/8 b = t  r  g = 2t/8 t  (5/6)b  5 = 128 t  (5/6)(2t/8)  5 = 128 Hope you're not too tired to finish it!
