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

### Instruction:
John buys 3 dress shirts.  They sell for $20 each.  He also has to pay 10% tax on everything.  How much did he pay in total?

### Response:
 $20 x 3 = <<20*3=60>>60.
$60 x 10/100 = <<60*10/100=6>>6.
$60 + $6 = <<60+6=66>>66.
