Abowl contains blueberries and strawberries. there are a total of 12 berries in the bowl. the ratio of blueberries to strawberries is 1 to 2. how many of each berry are in the bowl?

The answer to your question is There are 8 strawberries and 4 blueberries in the bowl.

Step-by-step explanation:

Data

Total berries = 12

Blueberry = b

Strawberry = s

Ratio  1 blueberry : 2 strawberries

Process

1.- Write equations

       b + s = 12       (I)

       2b = s             (II)

2.- Substitute equation 2 in equation I

       b + (2b) = 12

3.- Simplify

       3b = 12

         b = 12/3

4.- Result

        b = 4

5.- Find the value of s

       4 + s = 12

             s = 12 - 4

             s = 8

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
