A bag contained green and white stickers. There were 60% more green stickers than white stickers. When 130 more stickers were poured into the bag, the amount of green stickers increased by 25% and the amount of white stickers increased 90%. How many stickers were in the bag at first?

	Green stickers	White stickers	Total stickers
Before	8 u	5 u	13 u
Change	+ 2 u	+ 4.5 u	+ 6.5 u
After	10 u	9.5 u	19.5 u

100% + 60% = 160%

160% = ¹⁶⁰₁₀₀ = ⁸₅

Number of more green stickers that were poured into the bag
= 25% x 8 u
= ²⁵₁₀₀ x 8 u
= 2 u

Number of more white stickers that were poured into the bag
= 90% x 5 u
= ⁹⁰₁₀₀ x 5 u
= 4.5 u

Total number of more stickers that were poured into the bag
= 2 u + 4.5 u
= 6.5 u

6.5 u = 130

1 u = 130 ÷ 6.5 = 20

Number of stickers in the bag at first
= 8 u + 5 u
= 13 u
= 13 x 20
= 260

Answer(s): 260
