To find the cost of each folder first:
30/82.50 = 1/x
cross multiply:
30x = 82.50
find x.
x = 2.75
a journal is 10 times as much as a folder.
multiply.
2.75*10=27.50

How do I do this trying my best but I can’t please help T_T

Use algebra.

Let the number of stickers each had in the beginning = x stickers.

Ray lost 10 we represent this by

x - 10 ( = no. stickers he has now)

Tom bought 200 so the number of stickers he now has

= x + 200

Rays has 1/4 as much as Tom so we can now create the equation

1/4(x + 200) = x - 10

Soling for x:-

1/4 x + 50 = x - 10

60 = 3/4 x

x = 60 * 4/3 = 80

Answer they had 80 stickers at first.
