I'm not sure what the question is here. If an answer is communicative property, go with that. If it is asking for
, the answer is about 84.8230016469.
Now, if x = 300 miles, then
y= 1/20*300 + 35
y = 15 + 35
y = 50, therefore it would cost $50.00 to drive the rental car 300 miles.
X=3
Y=-2
Z=1
Hope this helps.
