Response to the following problem:
Henry, age 68, and Wilma, age 69, are married retirees who received the following income and retirement benefits during the year.
Fully taxable pension from Henry's former employer $8,800
Taxable interest 4,500
Social Security Benefits 2,400
Assume Henry and Wilma file a joint return, have no deductions for AGI, and do not itemize their deductions. Are they eligible for the tax credit for the elderly? If so, calculate the amount of the credit, assuming the credit is not limited by their income tax liability.
