One health insurance policy pays for people claims by multiplying the claim amount by 0,8 and then subtracting$500. Define a variable and write an equation for this situation. Find the claim amount for an insurance payment of $4650

$4650 represents the amount after the deductible of $500.
So before the deductible of $500, the insurable amount was $4650+500=$5150.
Since the payment rate is 0,8, the claimed amount was:
$5150/0,8=$6437,50
