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

### Instruction:
 Tiketi ya filamu inagharimu $5. Gharama ya popcorn ni 80% ya gharama ya tiketi na soda inagharimu 50% ya gharama ya popcorn. Familia ilinunua tiketi 4, seti 2 za popcorn, na soda 4. Walitumia kiasi gani?


### Response:
 Gharama ya popcorn ni $5 x 80/100 = $4.
Gharama ya soda ni $4 x 50/100 = $<<4*50/100=2>>2.
Gharama ya tiketi 4 ni $5 x 4 = $<<5*4=20>>20.
Gharama ya seti 2 za popcorn ni $4 x 2 = $<<4*2=8>>8.
Gharama ya soda 4 ni $2 x 4 = $<<2*4=8>>8.
Hivyo, familia ililipa jumla ya $20 + $8 + $8 = $<<20+8+8=36>>36.
