Answer:
400.29 hours
Explanation:
We can solve it using a rule of three, where we know that Kara earns $81 for working 12 hours and we want to know how many hours she works to earn $2702. Then:
$81 -------------- 12 hours
$2702 ---------- X
Where X is the number of hours that Kara works to earn $2702.
So, solving for X, we get:
[tex]X=\frac{2702\cdot12}{81}=400.29[/tex]Therefore, the answer is 400.29 hours
