Use reasoning to lead to the answer of the following question:
Mike has to get an x-ray and an MRI. The x-ray is $250 and the MRI is triple that cost. Insurance covers 80%. How much did he pay?

200
The MRI cost 250 * 3 = $750.

So between the two things he pays 250 + 750 = $1000.

Insurance covered 1000 *.

8 = $800.

So he had to pay 1000 - 800 = $200.

.

The final answer: 200
