Mr. Applegate, a disabled SSI recipient who is working, charges an IRWE which costs
                  $240 (i.e., purchase price plus applicable tax) on a credit card that has an annual
                  interest rate of 18%. Because there was already a balance on the account prior to
                  the IRWE purchase, you treat the IRWE as a nonrecurring expense.
               
               You calculate the interest on the IRWE purchase to be $43.20 ($240 × 18%). You determine
                  the deductible IRWE amount to be $283.20.
               
               You ask Mr. Applegate whether they want the IRWE amount deducted entirely in the month
                  charged or prorated over a consecutive 12-month period. They decide to have it prorated.
                  You deduct $23.60 ($283.20/12) a month as IRWE for 12 consecutive months beginning
                  with the month the IRWE was charged.
