You have been offered two different jobs from competing businesses. Company A is willing to pay you $120,000 a year if you commit to working for them for 40 years.  They have also promised a raise of 5% for every year you work.  Company B is also interested in you and is offering a base salary of $45,000 a year, but promises a 10% raise each year you work up until your 40th year with the firm.  Which is the better offer in regards to total dollars earned over the course of your career, and what is the total dollar difference between the two offers?
