Ready Fire Aim!
A target has three concentric circles. The bull's-eye is 10 points, the middle circle is x points, and the outer circle is 5 points. If three darts are thrown but only two hit the target, what are the possible totals? Assume that the point value increases as you get closer to the bull's-eye.
