The fare for riding a cab is as follows $ 1.40 for the first mile or part, $ 0.75 for each additional mile or part.
Determine an equation representing the cost of the ride in terms of the distance traveled
a) When C is less or equal to 0
b) When C is greater than 0

I have no clue how to set this up, haha. First time I have seen something like this... and beyond intuition I'm not confident enough at the moment, or too tired lol. Can someone explain thanks?

C = 0.75(n-1) + 1.4

I should slap myself in  the face, time to go to sleep haha. thanks man!

anonymous · Answer

it would be d instead of n since its a Cost function, right? and is that for A or B... if its B its not right :-/

hero · Answer

C = 1.40 + .75d

hero · Answer

We're assuming that C means cost. I don't know why we would worry about if C = 0. If C = 0 then there's no need for an equation. The cost will have to be at least 1.40. Anything less than that wouldn't make sense

anonymous · Answer

The answer was 1.4 without a variable for less than 0 or =. however, for the greater than equation C = 1.40 + .75d  isn't the right answer.

any idea, why the Web Work things that is wrong... when its seems to be right?
