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

	Opal	Tammy	Difference
Before	1 u + 26	1 u	26
Change	+ 38	+ 34
After	1 u + 64	1 u + 34	30
Comparing between Opal and Tammy in the end	5 p	3 p	2 p

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

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

Difference between the number of paper stars that Opal and Tammy folded in the end
= (1 u + 64) - (1 u + 34)
= 1 u + 64 - 1 u - 34
= 64 - 34
= 30

2 p = 30

1 p = 30 ÷ 2 = 15

Number of paper stars that Tammy folded
= 3 p
= 3 x 15
= 45

Answer(s): 45
