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

### Instruction:
Rachel drinks 2 glasses of water on Sunday and 4 glasses of water on Monday. Then she drinks 3 glasses of water every day for the next 4 days. One glass of water is 10 ounces of water. If Rachel wants to drink a total of 220 ounces of water in the week (Sunday to Saturday), how many glasses of water should she drink on Saturday?

### Response:
 Jumla ya glasi za maji Rachel amekunywa kutoka Jumapili hadi Jumatatu ni 2 + 4 = <<2+4=6>>6 glasi za maji.
Jumla ya unga wa maji Rachel amekunywa kutoka Jumapili hadi Jumatatu ni 6 x 10 = <<6*10=60>>60 unga wa maji.
Kutoka Jumanne hadi Ijumaa, Rachel ananywa glasi 3 x 4 = <<3*4=12>>12 za maji.
Jumla ya unga wa maji Rachel amekunywa kutoka Jumanne hadi Ijumaa ni 12 x 10 = <<12*10=120>>120 unga wa maji.
Jumla ya unga wa maji Rachel amekunywa kutoka Jumapili hadi Ijumaa ni 120 + 60 = <<120+60=180>>180 unga wa maji.
Unga wa maji anayopaswa kunywa siku ya Jumamosi ni 220 - 180 = <<220-180=40>>40 unga wa maji.
Rachel anapaswa kunywa 40/10 = <<40/10=4>>4 glasi za maji siku ya Jumamosi.
