Vanessa and Gabby folded paper stars over two days. On Thursday, Vanessa folded 18 paper stars more than Gabby. On Friday, Vanessa folded another 38 paper stars and Gabby folded another 16. At the end of the two days, Vanessa made ⁷₁₀ of the total number of stars. What was the number of paper stars that Vanessa folded?

	Vanessa	Gabby	Difference
Before	1 u + 18	1 u	18
Change	+ 38	+ 16
After	1 u + 56	1 u + 16	40
Comparing between Vanessa and Gabby in the end	7 p	3 p	4 p

Difference between the number of paper stars that Vanessa and Gabby folded in the end is repeated.

Difference between the number of paper stars that Vanessa and Gabby folded in the end
= 7 p - 3 p
= 4 p

Difference between the number of paper stars that Vanessa and Gabby folded in the end
= (1 u + 56) - (1 u + 16)
= 1 u + 56 - 1 u - 16
= 56 - 16
= 40

4 p = 40

1 p = 40 ÷ 4 = 10

Number of paper stars that Vanessa folded
= 7 p
= 7 x 10
= 70

Answer(s): 70
