Change	+ 34	+ 25
After	1 u + 55	1 u + 25	30
Comparing between Tammy and Jaslyn in the end	5 p	3 p	2 p

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

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

Difference between the number of paper stars that Tammy and Jaslyn folded in the end
= (1 u + 55) - (1 u + 25)
= 1 u + 55 - 1 u - 25
= 55 - 25
= 30

2 p = 30

1 p = 30 ÷ 2 = 15

Number of paper stars that Tammy folded
= 5 p
= 5 x 15
= 75

Answer(s): 75
