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

### Instruction:
Jack is on the phone with a scammer who says the IRS will arrest Jack if he doesn't send them the codes from 6 $500 Best Buy gift cards and 9 $200 Walmart gift cards. After sending the codes for 1 Best Buy gift card and 2 Walmart gift cards, Jack wises up and hangs up. How many dollars' worth of gift cards can he still return?

### Response:
 Kwanza tafuta idadi ya kadi za Best Buy ambazo Jack anahitaji kurudisha: kadi 6 - kadi 1 = <<6-1=5>>5 kadi
Kisha zidisha idadi hiyo na gharama ya kila kadi ili kupata kiasi cha kurudishiwa Jack kutoka Best Buy: 5 kadi * $500/kadi = $<<5*500=2500>>2500
Kisha tafuta idadi ya kadi za Walmart ambazo Jack anahitaji kurudisha: kadi 9 - kadi 2 = <<9-2=7>>7 kadi
Kisha zidisha idadi hiyo na gharama ya kila kadi ili kupata kiasi cha kurudishiwa Jack kutoka Walmart: 7 kadi * $200/kadi = $<<7*200=1400>>1400
Kisha ongeza kurudishiwa hizo mbili ili kupata jumla ya kiasi cha kurudishiwa: $2500 + $1400 = $<<2500+1400=3900>>3900
