(a)
Total number of stickers at first
=
1 u + 5 u + 161 + 10 u
= 16 u + 161
16 u + 161 = 36916 u = 369 - 16116 u = 208
1 u = 208 ÷ 16 = 13 Number of stickers that Glen had at first
= 5 u ÷
12= 5 u x
21= 10 u = 10 x 13 = 130(b)Total number of stickers that the three boys had at the end = 15 u = 15 x 13 = 195 Answer(s): (a) 130; (b) 195
