He had $75 he spent $9 he bought 3 posters that cost the same he had $27 left chat is the value of one poster

Answer 1

Let's denote the value of one poster as "x".

He started with $75 and spent $9, leaving him with $75 - $9 = $66.

Then, he bought 3 posters that cost the same, so he spent 3 * x.

After buying the posters, he had $27 left.

Therefore, we can write the equation:

$66 - 3x = $27

Now, let's solve for "x".

Adding 3x to both sides of the equation gives:

$66 = $27 + 3x

Subtracting $27 from both sides gives:

$66 - $27 = 3x

Simplifying the equation gives:

$39 = 3x

Dividing both sides by 3 gives:

x = $39 / 3

Simplifying the expression gives:

x = $13

So, the value of one poster is $13.
