Cecile packages snack mix at a health food store.She uses 1/3 of her supply of sunflower seeds to make a salted snack mix and 2/9 of her supply to make an unsalted snack mix. If Cecile uses 10 pounds of sunflower seeds, how many pounds of seeds are in her supply?
Accepted Solution
A:
Answer: her supply has 18 pounds
Explanation: Assume that the number of pounds in her supply is x. We are given that: She uses 1/3 x in salted mix and 2/9 x in unsalted mix. This means that: Total amount used = 1/3 x + 2/9 x = 5/9 x of her supply
Now, we are also given that: She used 10 pounds of her supply. This means that: 5/9 x = 10 5x = 9*10 = 90 x = 18 pounds
