Question 1099214
If cost of each vehicle is y=30+45x, then you can cancel choices 3 and 4.


Now you decide between choices 1 and 2.


y is already described as the cost for any car.  y depends on x, from the other member {{{30+45x}}}.   What could possibly vary for each car?  Either the size or the number of people inside.   Both choices 1 and 2 are badly described.


WHERE is the choice for 30 dollars basic car fee, 45 dollars PER PERSON, x for number of people in the car?
