Answer:
72
Step-by-step explanation:
The area of a polygon is sidelength * apothem * # of sides* (1/2)
That means the area is: 6 * 4 * 6 * (1/2) = 72
In more conventional notation, ...
b(x) = -15x² +450x +325 . . . . 0 ≤ x ≤ 24
For 1990, x = 1990 - 1983 = 7
b(7) = -15·7² +450·7 +325 = 2740
The value of the card in 1990 was 2740.
