Kathy and Marion folded paper cranes over two days. On Tuesday, Kathy folded 10 paper cranes more than Marion. On Wednesday, Kathy folded another 16 paper cranes and Marion folded another 4. At the end of the two days, Kathy made ⁵₈ of the total number of cranes. What was the number of paper cranes that Marion folded?

	Kathy	Marion	Difference
Before	1 u + 10	1 u	10
Change	+ 16	+ 4
After	1 u + 26	1 u + 4	22
Comparing between Kathy and Marion in the end	5 p	3 p	2 p

Difference between the number of paper cranes that Kathy and Marion folded in the end is repeated.

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

Difference between the number of paper cranes that Kathy and Marion folded in the end
= (1 u + 26) - (1 u + 4)
= 1 u + 26 - 1 u - 4
= 26 - 4
= 22

2 p = 22

1 p = 22 ÷ 2 = 11

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

Answer(s): 33
