Pamela and Asher collect pencils and erasers. Asher has 44 less pencils than erasers. Asher has 2 times the number of pencils Pamela has, and Pamela has 25% more erasers than Asher. After Pamela gives Asher all of her pencils and Asher gives Pamela 75% of his erasers, Asher has 39 less erasers than pencils. Find the number of erasers Pamela has at first.

Pamela		Asher
Erasers	Pencils	Erasers	Pencils
2.5 u + 55	1 u	2 u + 44	2 u
+ 1.5 u + 33	- 1 u	- 1.5 u - 33	+ 1 u
4 u + 88	0	0.5 u + 11	3 u

100%+ 25% = 125% 

125% x 2 u
= ¹²⁵₁₀₀ x 2 u
= 2.5 u

125% x 44
= ¹²⁵₁₀₀ x 44
= 55 

75% x 2 u
= ⁷⁵₁₀₀ x 2 u
= 1.5 u  

75% x 44 
= ⁷⁵₁₀₀ x 44
= 33 

If another 39 erasers are given to Asher, he will have equal number of erasers and pencils in the end.
3 u = 0.5 u + 11 + 39
3 u - 0.5 u = 50
2.5 u = 50

1 u = 50 ÷ 2.5 = 20

Number of erasers that Pamela has at first
= 2.5 u + 55
= 2.5 x 20 + 55
= 50 + 55
= 105
 
Answer(s): 105
