Jen and Barbara folded paper stars over two days. On Thursday, Jen folded 12 paper stars more than Barbara. On Friday, Jen folded another 22 paper stars and Barbara folded another 10. At the end of the two days, Jen made ⁵₈ of the total number of stars. What was the number of paper stars that Jen folded?

	Jen	Barbara	Difference
Before	1 u + 12	1 u	12
Change	+ 22	+ 10
After	1 u + 34	1 u + 10	24
Comparing between Jen and Barbara in the end	5 p	3 p	2 p

Difference between the number of paper stars that Jen and Barbara folded in the end is repeated.

Difference between the number of paper stars that Jen and Barbara folded in the end
= 5 p - 3 p
= 2 p

Difference between the number of paper stars that Jen and Barbara folded in the end
= (1 u + 34) - (1 u + 10)
= 1 u + 34 - 1 u - 10
= 34 - 10
= 24

2 p = 24

1 p = 24 ÷ 2 = 12

Number of paper stars that Jen folded
= 5 p
= 5 x 12
= 60

Answer(s): 60
