cost per hour = $3
so, the total cost per time is
cost per time= 3* number of hours
cost per time==3x
now, the company charges a $5 boarding rate
so, the rate is
[tex]\begin{gathered} \text{rate= boarding rate}+\text{cosper times} \\ reaplce \\ y=\text{ \$5+\$3x} \\ \text{reorder} \\ y=\text{ \$3x}+\text{\$5} \end{gathered}[/tex]I hope this helps you
