<human>:  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.
<bot>: How much money did the boys pay? ** The total amount of money collected from the boy's payment is 40*$50 = $<<40*50=2000>>2000
How many girls are at Lulu's party? ** There are four times as many boys at Lulu's party as girls, meaning there are 40/4 = <<40/4=10>>10 girls at the party.
How much money did the girls pay? ** since each boy paid twice the money that each girl paid to attend the party, each girl paid $50/2 = $<<50/2=25>>25
How much money did the girls pay? ** The total amount of money collected from the girl's payment is $25*10 = $<<25*10=250>>250
How much money did the boys and girls pay? ** The total amount of money collected at the party is $250+$2000 = $<<250+2000=2250>>2250
