An Uber driver charges $6 to pick up a passenger and 50 cents per mile for any trip.

Answer 1

P(x) = 6 + .5x

P(x) represents "the total price of the trip if x miles are traveled"

6 represents the fee for picking up the passenger.

.5 represents the 50 cents.

x represents the number of miles.

The six is in there a constant because it's a flat fee (it's always going to be at least six dollars, regardless of how many miles are traveled). Then we add the per-mile cost onto the six dollars. The per-mile cost is represented by .5x because it's fifty cents (.5 or .50) per (times) mile (x)

Answer 2

Price P(x)= 6 + 0.5x
