To find out how much a pencil costs, let's assume the cost of the pencil is "x" dollars.

Given that a pen costs twice as much as a pencil, we can say that the cost of the pen is 2x dollars.

Now, we are told that Susan spends $1.50 for a pen and a pencil. So, the total cost of the pen and the pencil is 1.50 dollars.

We can then set up the equation:

2x + x = 1.50

Adding the costs of the pen and the pencil together, we get:

3x = 1.50

To isolate the variable, we divide both sides of the equation by 3:

x = 1.50 / 3

Simplifying, we find that:

x = 0.50

Therefore, a pencil costs $0.50.
