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

Answer :

Let:

E = Earnings

t = Number of hours

a = Money per hour

so:

[tex]E(t)=at[/tex]

If she works 19 per week, then:

A week, has 7 days, so:

[tex]7\cdot19=133hours[/tex]

Therefore:

[tex]\begin{gathered} t=133 \\ a=21 \\ E(133)=21\cdot133=2793 \end{gathered}[/tex]
