Diana and Victoria folded paper stars over two days. On Monday, Diana folded 29 paper stars more than Victoria. On Tuesday, Diana folded another 34 paper stars and Victoria folded another 8. At the end of the two days, Diana made ⁷₉ of the total number of stars. What was the number of paper stars that Victoria folded?

	Diana	Victoria	Difference
Before	1 u + 29	1 u	29
Change	+ 34	+ 8
After	1 u + 63	1 u + 8	55
Comparing between Diana and Victoria in the end	7 p	2 p	5 p

Difference between the number of paper stars that Diana and Victoria folded in the end is repeated.

Difference between the number of paper stars that Diana and Victoria folded in the end
= 7 p - 2 p
= 5 p

Difference between the number of paper stars that Diana and Victoria folded in the end
= (1 u + 63) - (1 u + 8)
= 1 u + 63 - 1 u - 8
= 63 - 8
= 55

5 p = 55

1 p = 55 ÷ 5 = 11

Number of paper stars that Victoria folded
= 2 p
= 2 x 11
= 22

Answer(s): 22
