Please answer the following question by reasoning step-by-step.
John ends up damaging his hearing aids. He needs to replace both of them. They cost $2500 each. Insurance covers 80% of the cost. How much does he personally have to pay?

1000
The cost of the hearing aids is $2500 * 2 = $5000.

So insurance covers $5000 *.

8 = $4000.

That means it cost him $5000 - $4000 = $1000.

.

The final answer: 1000
