Answer:
She should forgo the repairs.
Explanation:
If she does the repair, the total costs would be:
$300,000+$50,000 = $350,000
And the loss would be:
$290,000 -$350,000 = -$60,000
If she doesn't do the repair, the total costs would be:
$300,000
And the loss would be:
$250,000 -$300,000 = -$50,000
So, if she doesn't do the repairs she minimizes the loss
