<human>:  Mike has to get an x-ray and an MRI. The x-ray is $250 and the MRI is triple that cost. Insurance covers 80%. How much did he pay?
<bot>: How much did the MRI cost? ** The MRI cost 250*3=$<<250*3=750>>750
How much did Mike pay? ** So between the two things he pays 250+750=$<<250+750=1000>>1000
How much did insurance cover? ** Insurance covered 1000*.8=$<<1000*.8=800>>800
How much did Mike have to pay? ** So he had to pay 1000-800=$<<1000-800=200>>200
