I. Write an expression for the sequence of operations described below. multiply 6 by 3, then double the result

What does \"Then double the results mean\"?

II. The cafeteria sold 2 fewer bowls of chicken soup than bowls of tomato soup. They sold 16 bowls of soup in all. How many bowls of chicken soup did the cafeteria sell?

Solution

I)

multiply 6 by 3, then double the result

expression:(6x3)x2

6x3 is 18

double the result means, 18+18 =36

II)

let number of bowls of tomato soup sold =t

given cafeteria sold 2 fewer bowls of chicken soup than bowls of tomato soup

so ,number of bowls of chicken soup sold =t-2

They sold 16 bowls of soup in all

=> (t)+(t-2)=16

=>2t-2=16

=>2t=16+2

=>2t=18

=>t=18/2

=>t=9

so,number of bowls of chicken soup sold =9-2

number of bowls of chicken soup sold =7

cafeteria sold 7 bowls of chicken soup
