Answer:
D. $180,000 in bank A, $240,000 in bank B, $240,000 in bank C
Step-by-step explanation:
She needs to deposit less than $250,000 in each bank in order to be able to have that sum of money insured, in this case she could deposit it this way:
$250,000
$250,000
$160,000
But that could be too risky and too on the verge of not being accepted, you she just takes $10,000 out of every $250,000 deposits to make them $240,00, and add it to the $160,000 deposit, so she is left with three deposits of:
$240,000
$240,000
$180,000
And with this she makes sure all of her deposits are insured by staying below the $250,000 limit.
