Question

the taxi charges a flat fee of $3.75, plus $1.50 per kilometer driven. What is the total cost of a 10 km trip?

Answer 1

$18.75

Explanation:

Let

y = Total cost

x = number of kilometers

The equation:

y = 3.75 + 1.50x

If x = 10 km

y = 3.75 + 1.50(10)

= 3.75 + 15

= 18.75

y = $18.75

y = Total cost = $18.75
