Along the Boston waterfront, in their play time, Paul and his friends played a rock throwing game to perfect their throwing accuracy.
The object of their game is twofold. For accuracy, they must hit designated areas of the target drawn on an abandoned rowboat near Clarke's Wharf.
They were also attempting to make number combinations that totaled 30.
The three target areas are marked 10, 20, and 30 points.
Each player gets three rocks, or three tries to score as many points as possible.
How many different ways (0 + 0 + 30 is different from 0 + 30 + 0) could the boys have scored 30 points?
