Answer:
number of games she plays = 5 games
Explanation:
Juanita told her dad that she won 80% of the card games she played yesterday.
Let x be the number of games she played
number of games times the percentage of games won is equal to the 4 games won. To remove % we divide by 100.
![x \cdot (80)/(100) = 4](https://img.qammunity.org/2019/formulas/mathematics/middle-school/3c9wil4a4wa1vgep1h5rdabiyggvf59ugj.png)
Multiply both sides by 100
![80x=400](https://img.qammunity.org/2019/formulas/mathematics/middle-school/ujld1dghdc2cp3b1ik1dr1lfe0vcckmuli.png)
Divide both sides by 80
x=5
So number of games she plays = 5 games
