Jean and Emma folded paper balls over two days. On Monday, Jean folded 10 paper balls more than Emma. On Tuesday, Jean folded another 26 paper balls and Emma folded another 14. At the end of the two days, Jean made ⁵₈ of the total number of balls. What was the number of paper balls that Jean folded?

	Jean	Emma	Difference
Before	1 u + 10	1 u	10
Change	+ 26	+ 14
After	1 u + 36	1 u + 14	22
Comparing between Jean and Emma in the end	5 p	3 p	2 p

Difference between the number of paper balls that Jean and Emma folded in the end is repeated.

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

Difference between the number of paper balls that Jean and Emma folded in the end
= (1 u + 36) - (1 u + 14)
= 1 u + 36 - 1 u - 14
= 36 - 14
= 22

2 p = 22

1 p = 22 ÷ 2 = 11

Number of paper balls that Jean folded
= 5 p
= 5 x 11
= 55

Answer(s): 55
