Roshel and Shannon folded paper stars over two days. On Monday, Roshel folded 15 paper stars more than Shannon. On Tuesday, Roshel folded another 33 paper stars and Shannon folded another 12. At the end of the two days, Roshel made ⁵₇ of the total number of stars. What was the number of paper stars that Roshel folded?

	Roshel	Shannon	Difference
Before	1 u + 15	1 u	15
Change	+ 33	+ 12
After	1 u + 48	1 u + 12	36
Comparing between Roshel and Shannon in the end	5 p	2 p	3 p

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

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

Difference between the number of paper stars that Roshel and Shannon folded in the end
= (1 u + 48) - (1 u + 12)
= 1 u + 48 - 1 u - 12
= 48 - 12
= 36

3 p = 36

1 p = 36 ÷ 3 = 12

Number of paper stars that Roshel folded
= 5 p
= 5 x 12
= 60

Answer(s): 60
