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:
[tex]620+970=1590[/tex]Both x-rays together cost $1590
Second, calculate the 80% of $1590, the result will represent the amount deducted by the insurance
[tex]\frac{80\cdot1590}{100}=1272[/tex]→ 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
[tex]1590-1272=318[/tex]So after paying an annual deductible of $200, he will pay $318 for the x-rays.
