Answer:
457.2$
Explanation:
Fred's age is 44 years ,therefore in accordance with IRIS table, cost for each month 1000$ coverage is 0.44$
Coverage taxable for each month=90000/1000*.44=39.6$
Coverage taxable for 12 months=39.6*12=475.2$
Fred already pays= 0.20*90.000/1000=18$
Amount taxable to be shown as income=475.2-18$= 457.2$
