Juanita told her dad that she won 80% of the card games she played yesterday. If she won 4 games, how many games did she play?
To find the total number of games Juanita played, we can use the formula:
Number of games played = (Number of games won) / (Percentage of games won)
Substituting the given values into the formula:
Number of games played = 4 / 0.80 = 5
Therefore, Juanita played 5 card games yesterday.
To find out how many games Juanita played, we can set up a simple algebraic equation. Let's assume that the total number of games Juanita played is represented by the variable "x".
According to the information given, Juanita won 80% of the card games she played yesterday. This means that she won 4 out of x games. We can express this as follows:
80% of x = 4
To solve this equation, we need to convert the percentage into decimal form. 80% is equivalent to 0.80. So, the equation becomes:
0.80x = 4
Now, we can solve for x by dividing both sides of the equation by 0.80:
x = 4 ÷ 0.80
x = 5
Therefore, Juanita played 5 games yesterday.

0.8x = 4
x = 4/0.8
x = 5
