The answer is 5i
i = √(-1)
√(-25) = √((-1)*25) = √(-1) * √25) = i * 5 = 5i
The answer to the problem is x=3
<span>There would be 9,000 tickets sold at the $12 price point and 25,000 tickets sold at the $6 price. (25,000 x 6 = $150,000. 9,000 x $12 = $108,000. $150,000 + $108,000 = $258,000).</span>
