Wendy and Gem folded paper cranes over two days. On Saturday, Wendy folded 19 paper cranes more than Gem. On Sunday, Wendy folded another 11 paper cranes and Gem folded another 14. At the end of the two days, Wendy made ⁵₈ of the total number of cranes. What was the number of paper cranes that Wendy folded?

	Wendy	Gem	Difference
Before	1 u + 19	1 u	19
Change	+ 11	+ 14
After	1 u + 30	1 u + 14	16
Comparing between Wendy and Gem in the end	5 p	3 p	2 p

Difference between the number of paper cranes that Wendy and Gem folded in the end is repeated.

Difference between the number of paper cranes that Wendy and Gem folded in the end
= 5 p - 3 p
= 2 p

Difference between the number of paper cranes that Wendy and Gem folded in the end
= (1 u + 30) - (1 u + 14)
= 1 u + 30 - 1 u - 14
= 30 - 14
= 16

2 p = 16

1 p = 16 ÷ 2 = 8

Number of paper cranes that Wendy folded
= 5 p
= 5 x 8
= 40

Answer(s): 40
