Sagot :

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
