Step 5.
The largest facility has a total electrical output three times that of
the smallest facility.
3(100) = 300
The other facility has an output which is 50 Mw more than half that of the
largest facility.

The total output of the three facilities is 600 Mw.
100 + 200 + 300 = 600
Thus, the answers check.
Example 3:
The winning team in a football game scored 7 points less than twice the score of
the losing team. If the total score of both teams was 35 points, what was the final
