Toby has an okay life working at a tire factory. He just got a raise and his current salary is $30,000 per year. The employment contract stipulates that the salary increases by $1,000 per year for every year that he works at the company. He is currently 30 years old and in his country everyone retires at age 55, so Toby currently expects to work for 25 more years.

Tobys is thinking of going for a 2 year full-time MBA next year. His current boss tells him that if he demonstrates his MBA skills after his 2 years of school, he can have his old job back with a $6,000 raise, and will still be eligible for subsequent annual $1,000 raises, but will still retire at age 55. Toby has some savings and is considering going to school for a 2 year degree at a total cost of $20,000 for both years. Although he thinks that school will improve his life, he is not sure if his MBA would be a good investment.

Is Tobys MBA a good investment? How much better or worse off will he be when he retires? (in his country, the interest rate is 0%) (no philosophy; just $$$)

Note- Toby earns $30,000 in the first of his remaining 25 years.
