d

A grid has a horizontal axis labeled Time (days) and a vertical axis labeled Grams of radionuclide. Two curves are drawn on the graph. All points given are approximate.

Curve A begins at (0,40), curves down and to the right with a slope that becomes increasingly less steep, and ends at (43,10). The curve passes through the following points:
- (10,30),
- (22,20),
- and (38,12).
Curve B begins at (0,32), curves down and to the right with a slope that becomes increasingly less steep, and ends at (40,0). The curve passes through the following points:
- (3,24),
- (8,16),
- and (16,8).
