To find the possible costs of one tube of paint, we need to determine the total cost of the paint tubes and easel combined.

Let the cost of one tube of paint be represented by x.

The total cost of the paint tubes and easel combined is given by:
3x + 15 = 25
3x = 10
x = 10/3 = 3.33

Therefore, the cost of one tube of paint is $3.33.
