(a)
Total number of stickers at first
=
1 u + 5 u + 4 + 20 u
= 26 u + 4
26 u + 4 = 49826 u = 498 - 426 u = 494
1 u = 494 ÷ 26 = 19 Number of stickers that Glen had at first
= 5 u ÷
14= 5 u x
41= 20 u = 20 x 19 = 380(b)Total number of stickers that the three boys had at the end = 15 u = 15 x 19 = 285 Answer(s): (a) 380; (b) 285
