A pen costs twice as much as a pencil. If Susan spends $ 1.50 for a pen and a pencil, how much does a pencil cost ?
Let x = pencil price, then 2x = pen price.
x + 2x = $1.50
Solve for x.
the answer is $0.75
First find the cost of pencils
$0.50
To find out how much a pencil costs, we first need to understand the relationship between the cost of a pen and a pencil.
Let's assume the cost of a pencil is x dollars. Since the pen costs twice as much as the pencil, the cost of the pen would be 2x dollars.
According to the problem, Susan spent $1.50 on a pen and a pencil. So, we can now create an equation using the given information:
2x + x = $1.50
Combining like terms, we get:
3x = $1.50
Now we solve for x by dividing both sides of the equation by 3:
x = $1.50 / 3
Using a calculator, we find:
x = $0.50
Therefore, a pencil costs $0.50.
