A:
Answer:Cost of a pound of chocolate chips: $3.5Cost of a pound of walnuts: $1.25Step-by-step explanation:x - cost of a pound of chocolate chipsy - cost of a pound of walnutsWe create two equations based on the information we have:3x+2y=138x+4y=33The whole point of these problems os to get rid of x or y. In this question, we can do this by multiplying both sides of the first equation by 2, and then subtracting it from the second equation:8x+4y=336x+4y=262x=7x=3.5Then we change x for 3.5 in the first equation:3×3.5+2y=1310.5+2y=132y=2.5y=1.25Hope this helps!
