Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
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?

### Response:
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 he paid 20*12=$<<20*12=240>>240 for the shirts
Tax added 240*.1=$<<240*.1=24>>24
So he paid 240+24=$<<240+24=264>>264 for the shirts
