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

### Instruction:
At a laundromat, it costs $4 for a washer and a quarter for every 10 minutes in the dryer. Samantha does 2 loads of laundry in the wash and then divides all the washed clothes equally into 3 separate dryers. If she lets the dryers run for 40 minutes each, how much does she spend altogether?

### Response:
 Samantha anatumia $4/kufulia * 2 kufulia = $<<4*2=8>>8 kwa kufulia.
Kila mashine ya kukausha inagharimu robo * 40/10 = 100 senti = $1
Mashine 3 za kukausha zinagharimu 1 * 3 = <<1*3=3>>3 dola
Jumla, Samantha anatumia 8 + 3 = <<8+3=11>>11 dola
