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

### Instruction:
There are four times as many boys at Lulu's party as girls. Each boy paid twice the money that each girl paid to attend the party. If there are 40 boys at the party and each boy paid $50 to attend the party, calculate the total amount of money collected at the party.

### Response:
 Kiasi jumla cha pesa kilichokusanywa kutoka malipo ya wavulana ni 40*$50 = $<<40*50=2000>>2000
Kuna wavulana mara nne zaidi katika sherehe ya Lulu kuliko wasichana, maana yake kuna wasichana 40/4 = <<40/4=10>>10 katika sherehe.
kwa kuwa kila mvulana alilipa mara mbili ya pesa ambayo kila msichana alilipa kuhudhuria sherehe, kila msichana alilipa $50/2 = $<<50/2=25>>25
Kiasi jumla cha pesa kilichokusanywa kutoka malipo ya wasichana ni $25*10 = $<<25*10=250>>250
Kiasi jumla cha pesa kilichokusanywa katika sherehe ni $250+$2000 = $<<250+2000=2250>>2250
