A person's hourly pay rate, r, is found by dividing the total amount

marishachu [46]

Translating the words into formula, we have

$r = \dfrac{p}{w}$

In fact, we have that the pay rate is the total payment divided by the number of hours worked.

We can solve this formula for w in two steps: starting from the formula above, multiply both sides by w:

$rw = p$

And then divide both sides by r:

$w = \dfrac{p}{r}$
