Nora and Jade folded paper balls over two days. On Tuesday, Nora folded 44 paper balls more than Jade. On Wednesday, Nora folded another 34 paper balls and Jade folded another 8. At the end of the two days, Nora made ⁷₉ of the total number of balls. What was the number of paper balls that Jade folded?

	Nora	Jade	Difference
Before	1 u + 44	1 u	44
Change	+ 34	+ 8
After	1 u + 78	1 u + 8	70
Comparing between Nora and Jade in the end	7 p	2 p	5 p

Difference between the number of paper balls that Nora and Jade folded in the end is repeated.

Difference between the number of paper balls that Nora and Jade folded in the end
= 7 p - 2 p
= 5 p

Difference between the number of paper balls that Nora and Jade folded in the end
= (1 u + 78) - (1 u + 8)
= 1 u + 78 - 1 u - 8
= 78 - 8
= 70

5 p = 70

1 p = 70 ÷ 5 = 14

Number of paper balls that Jade folded
= 2 p
= 2 x 14
= 28

Answer(s): 28
