Let x be the score Britney must bowl in the third game.
To have an average of at least 170, the sum of the scores in the three games must be at least 3*170=510.
Therefore, we can write the inequality:
160 + 150 + x ≥ 510
Simplifying and solving for x, we get:
x ≥ 200
Therefore, Britney must bowl a score of at least 200 in the third game to have an average of at least 170 for the three games.
Among the choices given, the only answer that represents a score of at least 200 is B, so it is the correct answer.
