Emily and Dana folded paper stars over two days. On Saturday, Emily folded 38 paper stars more than Dana. On Sunday, Emily folded another 12 paper stars and Dana folded another 26. At the end of the two days, Emily made ⁵₈ of the total number of stars. What was the number of paper stars that Dana folded?

	Emily	Dana	Difference
Before	1 u + 38	1 u	38
Change	+ 12	+ 26
After	1 u + 50	1 u + 26	24
Comparing between Emily and Dana in the end	5 p	3 p	2 p

Difference between the number of paper stars that Emily and Dana folded in the end is repeated.

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

Difference between the number of paper stars that Emily and Dana folded in the end
= (1 u + 50) - (1 u + 26)
= 1 u + 50 - 1 u - 26
= 50 - 26
= 24

2 p = 24

1 p = 24 ÷ 2 = 12

Number of paper stars that Dana folded
= 3 p
= 3 x 12
= 36

Answer(s): 36
