Sam needs to rent a van for a school field trip. Van Company A charges a one-time fee of $250 plus $10 for
each mile driven. Van Company B charges a one-time fee
of $150 plus $12 for each mile driven. Let x represent the
number of miles driven. Let y represent the total cost, in
dollars, to rent the van. Which system of equations models
this situation?

A. y=250-10x
y=150-12x

B. y=10x-250
y=12x-150

C. y=250x +10
y=150x +12

D. y=10x +250
y=12x +150
