Adm,Ming,and Clinton sold sandwiches in the ratio 4:7:3 to raise money for their scout troop.Ming sold 91 sandwiches. How may sa

bonufazy [111]

The ratio in which Adm, Ming and Clinton sold sandwiches = 4:7:3
Number of sandwiches sold by Ming = 91
Let us assume the common ratio to be = x
Then
7x = 91
x = 91/7
= 13
Then
The number of sandwiches sold by Adm = 4 * 13
   = 52
The number of sandwiches sold by Clinton = 3 * 13
      = 39
So
The total number of sandwiches
sold by Adm, Ming and Clinton = 52 + 91 + 39
      = 182.
So a total of 182 sandwiches were sold by Adm, Ming and Clinton.
