Question

Which Student makes a wage of $21 per hour

Answer 1

The student that makes a wage of $21 per hour is Tarek.

Step by step explanation:

To determine which student makes a wage of $21 per hour, we need to divide the total earned by the number of ours, to see what is the rate per hour of each one:

Amy:

`(68)/(3)=22.67`

Tarek:

`(105)/(5)=\text{ \$21}`

For Kal and Paula, we need to cross multiply (proportional relationships) to get a rate for 60 minutes:

Kal:

`\begin{gathered} (8)/(20)=(x)/(60) \\ 20x=480 \\ x=(480)/(20)=\text{ \$24} \end{gathered}`

Paula:

`\begin{gathered} (29)/(75)=(x)/(60) \\ x=(29\cdot60)/(75) \\ x=(1740)/(75)=\text{ \$23.2} \end{gathered}`

Therefore, the student that makes a wage of $21 per hour is Tarek.
