Answer:
$2.25 per kilometer
Step-by-step explanation:
Here we are asked for the unit rate, dollar per kilometer, that is [tex]\$/km[/tex].
If Emanuel was charged $32 we need to divided that amount by the kilometers traveled, so:
[tex]x=\frac{\$32}{(14+\frac{2}{9})km}\\x=\frac{\$32}{\frac{128}{9}km}\\\\x= \frac{\$288}{128km}\\\\x=2.25\frac{\$}{km}[/tex]
So the cost per kilometer traveled is $2.25.
