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

### Instruction:
Matilda had 20 chocolate bars and shared them evenly amongst herself and her 4 sisters. When her father got home from work, he was upset that they did not put aside any chocolates for him. They felt bad, so they each gave up half of their chocolate bars for their father. Their father then gave 3 chocolate bars to their mother and ate 2. How many chocolate bars did Matilda's father have left?

### Response:
 Matilda na dada zake kila mmoja alipata mikate ya chokoleti 20 / watu 5 = <<20/5=4>>4 mikate ya chokoleti/kila mtu.
Kila mmoja wao alitoa 1/2 * mikate 4 = <<4*1/2=2>>2 mikate ya chokoleti kwa baba yao.
Baba yao alipokea 1 * 2 mikate ya chokoleti = <<1*2=2>>2 mikate ya chokoleti kutoka kwa kila mtu, hivyo alikuwa na mikate 2 * watu 5 = <<2*5=10>>10 ya chokoleti.
Baba yao alijiondolea mikate 10 - mikate 2 - mikate 3 = <<10-2-3=5>>5 ya chokoleti.
