Answer:
$850000
Step-by-step explanation:
Dennis ( SINGLE ACCOUNT ) = $300000
Rhonda (single account ) = $100000
Dennis and Rhonda ( joint account ) = $400000
Rhonda and Blake (joint account ) = $100000
The FDIC will insure individual accounts up to the tune of $250000 and also shares of each individual in every joint account will also be insured as well
From Dennis single account : $250000 is insured
From Rhonda single account : $100000 is insured
from Dennis share in the joint account with Rhonda : $200000 is insured
likewise Rhonda's share which is also : $200000
Rhonda and Blake shares from their joint account will be insured as well : $10000
Total insured amount by FDIC = 250000 + 100000 + 200000 +200000 +100000 = $850000
