Problem
Tanijah, age 64, earned 35 credits over the last 9 years of working part time with a non-profit organization which was his only occupation in the country and earned $5,100 per year. At the end of this year, he intends to retire and collect Social Security benefit and Medicare. Will he be able to retire if he earns the same salary this year given that it takes $1275 of earnings to earn each credit?
