Question

A taxi fare is $3 and then $0.40 for every kilometre. A taxi fare is $9 . How far has the taxi travelled?

Answer 1

y = 3 + 0.40x

Explanation:

Fixed cost of taxi fare = $3

Additional cost = $0.40

y = Total cost

x = number of kilometers

The equation:

Total cost = Fixed cost of taxi fare + (Additional cost * number of kilometers)

y = 3 + 0.40x
