He bought 5*4=<<5*4=20>>20 shirts

The discount saves him 15*.2=$<<15*.2=3>>3 per shirt

So each shirt cost 15-3=$<<15-3=12>>12

So the total order cost 20*12=$<<20*12=240>>240

Tax added 240*.1=$<<240*.1=24>>24

So he paid 240+24=$<<240+24=264>>264

Tom decides to buy some shirts from his favorite fandoms because there is a sale on his favorite website.  He buys 5 t-shirts from each of his 4 favorite fandoms.  The shirts normally cost $15 each but there is a 20% off sale.   The order qualified for free shipping but he still needed to pay 10% tax.  How much did he pay?
