Guess+and+Check+1Y

KF-60 In the football game, Rocky gained 3 times as many yards as Bullwinkle. Rocky also gained 10 yards more than Boris. The 3 players gained a total of 410 yards. How many yards did Boris gain?

Guess and Check Table Rocky's yds. Bullwinkle's yds. Boris's yds. total 410? actual answer 180 60 170 yes 410

What I did was I just picked a random number that I thought would be correct. Then I did the extra math and figured out what Bullwinkle's yards was by dividing it by 3. After that I subtracted 10 from Rocky's yards and added all of the totals. And I found out that my guess was correct.
