Fanny and Shannon folded paper stars over two days. On Tuesday, Fanny folded 8 paper stars more than Shannon. On Wednesday, Fanny folded another 39 paper stars and Shannon folded another 11. At the end of the two days, Fanny made ⁵₇ of the total number of stars. What was the number of paper stars that Shannon folded?

	Fanny	Shannon	Difference
Before	1 u + 8	1 u	8
Change	+ 39	+ 11
After	1 u + 47	1 u + 11	36
Comparing between Fanny and Shannon in the end	5 p	2 p	3 p

Difference between the number of paper stars that Fanny and Shannon folded in the end is repeated.

Difference between the number of paper stars that Fanny and Shannon folded in the end
= 5 p - 2 p
= 3 p

Difference between the number of paper stars that Fanny and Shannon folded in the end
= (1 u + 47) - (1 u + 11)
= 1 u + 47 - 1 u - 11
= 47 - 11
= 36

3 p = 36

1 p = 36 ÷ 3 = 12

Number of paper stars that Shannon folded
= 2 p
= 2 x 12
= 24

Answer(s): 24
