Answer provided by our tutors
A) What were the total private health expenditures in 2000(t)=10?
t= 10
H = 2(10) + 411 =431 billion --> the final answer
H = 2(2000) + 411= 4411 billion
B) In what year will total private health expenditures be $879 billion?(Use a table with triangle(t)=1)
879 = 2t + 411
t = 234
1990+234 = 2224 --> year
C) In what year will private health expenditures exceed $1 trillion?($1,000 billion)
1000 = 2t + 411
t = 294.5
year: 1990+ 294.5 = 2284
