Gillian and Kimberly folded paper stars over two days. On Monday, Gillian folded 24 paper stars more than Kimberly. On Tuesday, Gillian folded another 33 paper stars and Kimberly folded another 27. At the end of the two days, Gillian made ⁵₈ of the total number of stars. What was the number of paper stars that Gillian folded?

	Gillian	Kimberly	Difference
Before	1 u + 24	1 u	24
Change	+ 33	+ 27
After	1 u + 57	1 u + 27	30
Comparing between Gillian and Kimberly in the end	5 p	3 p	2 p

Difference between the number of paper stars that Gillian and Kimberly folded in the end is repeated.

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

Difference between the number of paper stars that Gillian and Kimberly folded in the end
= (1 u + 57) - (1 u + 27)
= 1 u + 57 - 1 u - 27
= 57 - 27
= 30

2 p = 30

1 p = 30 ÷ 2 = 15

Number of paper stars that Gillian folded
= 5 p
= 5 x 15
= 75

Answer(s): 75
