Victoria and Gem folded paper balls over two days. On Wednesday, Victoria folded 33 paper balls more than Gem. On Thursday, Victoria folded another 21 paper balls and Gem folded another 26. At the end of the two days, Victoria made ⁵₈ of the total number of balls. What was the number of paper balls that Victoria folded?

	Victoria	Gem	Difference
Before	1 u + 33	1 u	33
Change	+ 21	+ 26
After	1 u + 54	1 u + 26	28
Comparing between Victoria and Gem in the end	5 p	3 p	2 p

Difference between the number of paper balls that Victoria and Gem folded in the end is repeated.

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

Difference between the number of paper balls that Victoria and Gem folded in the end
= (1 u + 54) - (1 u + 26)
= 1 u + 54 - 1 u - 26
= 54 - 26
= 28

2 p = 28

1 p = 28 ÷ 2 = 14

Number of paper balls that Victoria folded
= 5 p
= 5 x 14
= 70

Answer(s): 70
