I would say $450 because of the $1250, $250 is the deductible so has to be paid by you, and then of the $1000 remaining you have to pay 20% so 0.2 x 1000=$200 so the total is $250+$200=$450. Without the insurance you would have had to pay the full $1250 so you saved $800 by having the insurance.
Dancing involves a lot of muscles.. it depends what kind of dancing and it’s health related because it helps with your breathing and breathing patterns.
