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

### 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:
The total amount of money collected from the boy's payment is 40*$50 = $<<40*50=2000>>2000
The number of girls at the party is 1/4*40 = <<1/4*40=10>>10
Each girl paid 1/2*$50 = $<<1/2*50=25>>25 to attend the party.
The total amount of money collected from the girl's payment is $25*10 = $<<25*10=250>>250
The total amount of money collected at the party is $250+$2000 = $<<250+2000=2250>>2250
