Tina and Roshel folded paper stars over two days. On Friday, Tina folded 41 paper stars more than Roshel. On Saturday, Tina folded another 13 paper stars and Roshel folded another 14. At the end of the two days, Tina made ⁷₁₀ of the total number of stars. What was the number of paper stars that Tina folded?

	Tina	Roshel	Difference
Before	1 u + 41	1 u	41
Change	+ 13	+ 14
After	1 u + 54	1 u + 14	40
Comparing between Tina and Roshel in the end	7 p	3 p	4 p

Difference between the number of paper stars that Tina and Roshel folded in the end is repeated.

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

Difference between the number of paper stars that Tina and Roshel folded in the end
= (1 u + 54) - (1 u + 14)
= 1 u + 54 - 1 u - 14
= 54 - 14
= 40

4 p = 40

1 p = 40 ÷ 4 = 10

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

Answer(s): 70
