Question

Christi earns $21 per hour working as a receptionist. If she works 19 hours per week, what is her weekly wage?

Answer 1

Let:

E = Earnings

t = Number of hours

a = Money per hour

so:

`E(t)=at`

If she works 19 per week, then:

A week, has 7 days, so:

`7\cdot19=133hours`

Therefore:

`\begin{gathered} t=133 \\ a=21 \\ E(133)=21\cdot133=2793 \end{gathered}`
