Answer:
$220
Step-by-step explanation:
Basically, the insurance company does these 3 things:
Takes the statement of covered charges
Subtracts 100 dollars from it
Pays 80% of the remaining
So,
Sean has covered charges of 700
Insurance company deducts 100, so remaining is 700 - 100 = 600
Now insurance company pays 80% of this, 600 * 0.8 = 480
Now,
$480 is paid off by insurance company, so Sean has to pay the remaining. Which is:
700 - 480 = $220
