Answer 1

Taryn earns $112.50 in 7.5 hours.

Alastair earns $122.50 in 5 hours.

Let us calculate what each earn per hour

$\begin{gathered} \text{Taryn earning per hour} \\ \text{amount per hour=}\frac{112.50}{7.5}=\text{ \ 15} \end{gathered}$$\begin{gathered} \text{Alastair earning per hour} \\ \text{amount per hour=}\frac{122.50}{5}=\text{ \ }24.5 \end{gathered}$

Therefore,

Alastair earns more per hour than Taryn.
