Answer:
Each pound of chocolate chips costs $ 1.5 and each pound of walnuts cost $ 3.75 .
Step-by-step explanation:
Let, each pound of chocolate chips costs $ x and each pound of walnuts costs $ y.
Then, according to the question,
5x + 6y = 30 --------------(1) and,
3x + 2y = 12 ----------------(2)
Multiplying (2) by 3 we get,
9x + 6y = 36 ---------------------(3)
Deducting (1) from (3) we get,
4x = 6
⇒ x = 1.5 ----------------------(4)
From (4), putting the value of x in (2) , we get,
2y = 7.5
⇒ y = 3.75 ---------------------------(5)
