Question

Which Student makes a wage of $21 per hour

Answer 1

Answer:

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:

$\frac{68}{3}=22.67$

Tarek:

$\frac{105}{5}=\text{ \ 21}$

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

Kal:

$\begin{gathered} \frac{8}{20}=\frac{x}{60} \\ 20x=480 \\ x=\frac{480}{20}=\text{ \ 24} \end{gathered}$

Paula:

$\begin{gathered} \frac{29}{75}=\frac{x}{60} \\ x=\frac{29\cdot60}{75} \\ x=\frac{1740}{75}=\text{ \ 23.2} \end{gathered}$

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