For this case, the first thing we must do is define variables.
We have then:
x: initial amount of cards
We now write the equation that models the problem:
[tex] x - (\frac{1}{2}) x - (\frac{1}{4}) x = 75
[/tex]
[tex] (\frac{1}{4}) x = 75
x = 75 * 4
x = 300
[/tex]
Therefore, the initial amount of cards is 300
Answer:
Latoya had 300 cards at the beginning
