Number of stickers that Jeremy had in the end
= 2 x 5 u
= 10 u
Number of stickers that Glen had in the end
= 4 x 5 u
= 20 u
Total number of stickers at first
= 10 u + 5 + 6 u + 20 u - 12
= 36 u - 7
36 u - 7 = 245
36 u = 245 + 7
36 u = 252
1 u = 252 ÷ 36 = 7
Number of stickers that Glen had at first
= 20 u - 12
= 20 x 7 - 12
= 140 - 12
= 128
Answer(s): 128
