Answer:
Her score in the first game was 173.
Step-by-step explanation:
Sue's total score for the 3 games = 3*162 = 486 points.
Let her score in the first game be x points. Then in the second game she scored (x - 10) and in the third, ( x - 10 - 13) points:
x + (x - 10) + (x - 23) = 486
3x - 33 = 486
3x = 519
x = 173 (answer).
<u>Answer:</u>
173
<u>Step-by-step explanation:</u>
Assuming x to be Sue's score in the first game, the score in her second game would be (x-10) and (x-10-13).
Also, we know that the average score for these three bowling games was 162 so we can write:
Therefore, Sue scored 173 in her first game.
