Step-by-step explanation:
mean of men=sum/no of men
177=sum/30
sum=177*30
= 5310
mean of women=sum/no of women
164=sum/16
sum=164*16

mean height= (5310+2624)/30+16

Answer: There were 350 hamburgers sold.
Step-by-step explanation:
x + (x +73)= 773 where x is the number of hamburgers sold and (x+ 73) is the number of cheese burgers sold.
x + (x+ 73)=773
2x + 73 = 773
2x + 700
x= 350
1(350)= 350
