Jason has long wanted to drive as an independent trucker, but the rental price for the truck Jason wanted is $6,000 per month and that was more than he could afford. For his 30th birthday, Jason’s father bought Jason the truck as a gift. Jason started driving the new truck as an independent trucker and was earning revenues of $18,000 a month with expenses of $13,000 a month (excluding any salary). He was recently bragging to a friend that he was clearing $5,000 a month from his business, which was better than the $4,000 a month he was making as a truck driver for his former employer, Global Shipping.
