Solve the problem involving modeling with polynomial functions.For this problem, y-values correspond to the amount spent by Country X on imports (in millions of dollars) over the years 1986 (x = 0), through 1993 (x = 7). (a) Use the data given in the table below to determine a quartic (fourth-degree) polynomial model. 
(b) Based on the quartic model, how much was spent on imports in 1987?
A. (a) y ? 0.0475x4 - 0.727500x3 + 3.394
x2 - 4.12
x + 1.69;
(b) $3.65 million
B. (a) y ? 0.0475x4 - 0.727500x3 + 3.394
x2 - 4.12
x + 1.69;
(b) $0.28 million
C. (a) y ? 0.0475x4 - 0.727500x3 + 3.394
x2 - 4.12
x + 1.69;
(b) $3.55 million
D. (a) y ? 0.0475x4 - 0.727500x3 + 3.394
x2 - 4.12
