Julie is thinking about the best way to get to a customers workplace. She has two options. The first is that she can use a pool car that is used by staff at her workplace for business travel purposes or the second option is to drive her own car at a marginal cost of $0.78 cents per kilometre and be reimbursed by her workplace at a rate of $0.70 cents per kilometre. What would be the relevant net cost if Julie decides to use her own car?
