Question

HELP!!!! In Ottawa you can ride on a tour bus for a fixed price plus a variable amount that depends on the length of the trip. the variable cost is $2/km and 20km trip cost $55

Determine the equation relating cost, C, in dollars, and distance, d, in kilometers.

Answer 1

C = 2d + 15

Explanation:

$2 per km, so $40 for 20km.

55-40 is 15 so $15 is a fixed price.

Hence, C = 2d + 15
