Lucy and Olivia folded paper stars over two days. On Monday, Lucy folded 14 paper stars more than Olivia. On Tuesday, Lucy folded another 27 paper stars and Olivia folded another 15. At the end of the two days, Lucy made ⁵₈ of the total number of stars. What was the number of paper stars that Lucy folded?

	Lucy	Olivia	Difference
Before	1 u + 14	1 u	14
Change	+ 27	+ 15
After	1 u + 41	1 u + 15	26
Comparing between Lucy and Olivia in the end	5 p	3 p	2 p

Difference between the number of paper stars that Lucy and Olivia folded in the end is repeated.

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

Difference between the number of paper stars that Lucy and Olivia folded in the end
= (1 u + 41) - (1 u + 15)
= 1 u + 41 - 1 u - 15
= 41 - 15
= 26

2 p = 26

1 p = 26 ÷ 2 = 13

Number of paper stars that Lucy folded
= 5 p
= 5 x 13
= 65

Answer(s): 65
