Answer:
The cost for each pound of chocolate chips is $2.75 and the cost for each pound of walnuts is $3.75.
Step-by-step explanation:
9x+7y=51
3x+5y=27
----------------
9x+7y=51
-3(3x+5y)=-3(27)
-------------------------
9x+7y=51
-9x-15y=-81
-------------------
-8y=-30
8y=30
y=30/8
simplify,
y=15/4
9x+7(15/4)=51
9x+105/4=51
9x=51-105/4
9x=(204-105)/4
9x=99/4
x=(99/4)/9
x=(99/4)(1/9)=99/36
simplify
x=2.75
So the cost for each pound of chocolate chips is $2.75 and the cost for each pound of walnuts is $3.75.
