Hey guys,
The final answer for this problem is 0.3977272727272. The only accepted answer is .398, which seems to be a random acceptable answer since it is not specified that 3 decimal places are accepted. I think that .4, .398 and .3977 should all be acceptable answers. These problems take too long to fall back on a technicality.
