Answer:
Step-by-step explanation:
According to the problem, Sarah's percentage of successful free throws is 75%, this means that she failed a 25% of the total. If the total free throws are 12, then:
[tex]12(0.25)=3[/tex]
(Remember that, 25% is divided by 100, to have the decimal expression of this percentage)
Therefore, Sarah missed 3 free throws during the game.
