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=}(112.50)/(7.5)=\text{ \$15} \end{gathered}`
`\begin{gathered} \text{Alastair earning per hour} \\ \text{amount per hour=}(122.50)/(5)=\text{ \$}24.5 \end{gathered}`

Therefore,

Alastair earns more per hour than Taryn.
