Kudos for the right answer and explanation
Percentage of expenditure for physician services in 1989 is 20%.
Approximate expenditure for physician services = 550 x 20/100 --> $110 billion.
Percentage of expenditure for nursing care in 1989 is 8%.
Approximate expenditure for nursing care = 550 x 8/100 --> $44 billion.
110 - 44 = $66 billion is the expenditure for physician services more than expenditure for nursing care. Hence option B is the correct answer.
