Answer:
The team must win 25 games to finish the season winning 80% of the games
Explanation:
The soccer team has won 60%, that is:
25 games * 60% = 15 games has won.
We can solve this problem with the equations:
25 games + X = Y <em>(1)</em>
<em>Where Y are total games, and X the additional games the soccer team must win.</em>
15 games + X = 0.8Y <em>(2)</em>
<em>In therms of winning games.</em>
<em />
Subtracting 1 - 2:
10 games = 0.2Y
50games = Y
And X is:
25 games + X = Y <em>(1)</em>
25 games + X = 50games <em>(1)</em>
X = 25 games
<h3>The team must win 25 games to finish the season winning 80% of the games</h3>
