The cost of having your car towed is 45 to hook up the carand then 3.50 per mile towed. which equation models your total cost?
A. y=40x+3.50 B. y=3.50x+45 c. y=48.50x D. x+y=48.50
y represents the total cost x represents the number of miles towed (since it costs 3.50 per one mile, that's why the variable x needs to be here because we don't know how many miles we'll have yet)
