Roshel and Gwen folded paper balls over two days. On Tuesday, Roshel folded 32 paper balls more than Gwen. On Wednesday, Roshel folded another 10 paper balls and Gwen folded another 6. At the end of the two days, Roshel made ⁷₁₀ of the total number of balls. What was the number of paper balls that Roshel folded?

	Roshel	Gwen	Difference
Before	1 u + 32	1 u	32
Change	+ 10	+ 6
After	1 u + 42	1 u + 6	36
Comparing between Roshel and Gwen in the end	7 p	3 p	4 p

Difference between the number of paper balls that Roshel and Gwen folded in the end is repeated.

Difference between the number of paper balls that Roshel and Gwen folded in the end
= 7 p - 3 p
= 4 p

Difference between the number of paper balls that Roshel and Gwen folded in the end
= (1 u + 42) - (1 u + 6)
= 1 u + 42 - 1 u - 6
= 42 - 6
= 36

4 p = 36

1 p = 36 ÷ 4 = 9

Number of paper balls that Roshel folded
= 7 p
= 7 x 9
= 63

Answer(s): 63
