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

### Instruction:
A movie theater company is advertising a deal of a movie ticket, a bucket of popcorn, a drink, and a box of candy for $20. Normally, a movie ticket costs $8, a bucket of popcorn costs three dollars less, a drink costs a dollar more than popcorn, and a candy costs half as much as a drink. How many dollars does the deal save a customer who buys a ticket, popcorn, drink, and candy normally?

### Response:
 Kwanza, tafuta bei ya popcorn kwa kutoa dola tatu kutoka bei ya tiketi ya sinema: $8 - 3 = $<<8-3=5>>5
Kisha tafuta bei ya kinywaji kwa kuongeza dola moja kwenye bei ya popcorn: $5 + 1 = $<<5+1=6>>6
Kisha tafuta bei ya pipi kwa kugawanya nusu ya bei ya kinywaji: $6 / 2 = $<<6/2=3>>3
Kisha tafuta bei ya vitu vyote vinne unaponunua kila kitu kivyake kwa kuongeza gharama ya kila kitu: $8 + $5 + $6 + $3 = $<<8+5+6+3=22>>22
Kisha toa bei ya ofa kutoka kwenye bei ya kununua kila kitu kivyake ili kupata akiba: $22 - $20 = $<<22-20=2>>2
