Question

39. Each gram of birdseed is made up of 3 parts water, 2 parts powder, and 1 part special additi a 7 day supply of 24 grams per day. how many grams of powder do you have? A. 168 B. 56*C.12D.84

Answer 1

7 day supply -> 1 day supply is 24 grams of birdsees

According to the previous information, you have enough supplies for 7 days of 24 grams/day , that means, that you total supply is 168 grams

$7\cdot24=168$

Now, from that total supply, you need to determine how much powder you have. Based on the following:

birdseed is made up of -> 3 parts W + 2 parts P + 1 part S -> 6 parts in total

So, if powder represents 2 parts from a total of 6, that means that powder is 2/6 of the birdseed, therefore, we need to calculate 2/6 of 168 grams

$\frac{2}{6}\cdot168$

this is 56, so the answer is option B

$\frac{2}{6}\cdot168=\frac{2\cdot168}{6}=\frac{336}{6}=56$
