kaheart [24]

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}
