Welcome to Fluther.

We don’t really “do” homework here (when we can help ourselves), but we have no problem with helping YOU do it.

You’ve been given the value for one variable, which is the pay rate: $8 / hour.

You want to find the total pay, which we can call “P” (or any other variable name that makes sense to you).

Your definition of the problem includes the name of the other variable, “H”, which is hours worked. You already have one value assigned to this; you can assign more values as you need to.

So, to state the problem in words (recapping what you already have above): What is my pay if I work an unknown number of hours, H, and earn $8 for every one of those hours?

In full, the equation is:

P = $8 / hr. * H hrs.

The “hr.” elements cancel (since one is a multiplicand and one is a divisor), and we’re left with:

P = $8 * H

P = $8 * 36

Your answer will be expressed in dollars, which is what the question asks.
