(a)
Total number of stickers at first
=
1 u + 4 u + 232 + 8 u
= 13 u + 232
13 u + 232 = 40113 u = 401 - 23213 u = 169
1 u = 169 ÷ 13 = 13 Number of stickers that Elijah had at first
= 4 u ÷
12= 4 u x
21= 8 u = 8 x 13 = 104(b)Total number of stickers that the three boys had at the end = 12 u = 12 x 13 = 156 Answer(s): (a) 104; (b) 156
