The money owed out of pocket for the bill will be $845
Explanation:
The formula would be
(30% (Insurance cost-deductible cost)) + deductible cost + co payment
=(30 percentage of ($1000(insurance)-$750( deductible) + $20))+$750( deductible)+$20(co-payment)
= (30%($250)) +$750+ $20
=$75 + $750+$20 = $845
The solution is $845.
