Carl caused a car accident that resulted in $40,000 worth of property damage and $70,000 worth of medical bills. If Carl's insurance company will pay 80% of the costs, leaving Carl to pay the remaining 20%, how much does Carl personally owe?
First find the total cost of the accident: $40,000 + $70,000 = $
<gadget id="calculator">40000+70000</gadget>
<output>110_000</output>
110,000.
Then multiply the total cost by the percentage Carl has to pay to find his personal cost: $110,000 * .2 = $
<gadget id="calculator">110000*.2</gadget>
<output>22_000</output>
22,000.

<result>22_000</result>
