At the end of the two days, Tammy made ⁵₈ of the total number of stars. What was the number of paper stars that Tammy folded?

	Tammy	Emma	Difference
Before	1 u + 35	1 u	35
Change	+ 22	+ 29
After	1 u + 57	1 u + 29	28
Comparing between Tammy and Emma in the end	5 p	3 p	2 p

Difference between the number of paper stars that Tammy and Emma folded in the end is repeated.

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

Difference between the number of paper stars that Tammy and Emma folded in the end
= (1 u + 57) - (1 u + 29)
= 1 u + 57 - 1 u - 29
= 57 - 29
= 28

2 p = 28

1 p = 28 ÷ 2 = 14

Number of paper stars that Tammy folded
= 5 p
= 5 x 14
= 70

Answer(s): 70
