The insurance policy covers 80% of the cost of x-rays after paying an annual deductible.
The first x-ray costs $620
The second x-ray costs $970
First, you have to add the cost of both x-rays to determine how much do they cost:
Both x-rays together cost $1590
Second, calculate the 80% of $1590, the result will represent the amount deducted by the insurance
→ The amount covered by the insurance is $1272
Third, subtract the discount to the total cost of the x-rays to determine how much will he pay
So after paying an annual deductible of $200, he will pay $318 for the x-rays.
