At first
Difference in the number of stickers
= 80 - 50
= 30
In the end
Difference in the number of stickers in units
= 6 u - 1 u
= 5 u
The difference in the number of stickers between the green stickers and the blue stickers remains unchanged.
5 u = 30
1 u = 30 ÷ 5 = 6
Number of green stickers that Adam gives away
= 50 - 6
= 44
Total number of stickers that Adam gives away
= 2 x 44
= 88
Answer(s): 88
