Cindy and Jaslyn folded paper cranes over two days. On Thursday, Cindy folded 9 paper cranes more than Jaslyn. On Friday, Cindy folded another 19 paper cranes and Jaslyn folded another 6. At the end of the two days, Cindy made ⁵₈ of the total number of cranes. What was the number of paper cranes that Jaslyn folded?

	Cindy	Jaslyn	Difference
Before	1 u + 9	1 u	9
Change	+ 19	+ 6
After	1 u + 28	1 u + 6	22
Comparing between Cindy and Jaslyn in the end	5 p	3 p	2 p

Difference between the number of paper cranes that Cindy and Jaslyn folded in the end is repeated.

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

Difference between the number of paper cranes that Cindy and Jaslyn folded in the end
= (1 u + 28) - (1 u + 6)
= 1 u + 28 - 1 u - 6
= 28 - 6
= 22

2 p = 22

1 p = 22 ÷ 2 = 11

Number of paper cranes that Jaslyn folded
= 3 p
= 3 x 11
= 33

Answer(s): 33
