Question

A store is having a sale on chocolate chips and walnuts. For 4 pounds of chocolate chips and 8 pounds of walnuts, the total cost is $33. For 2 pounds of chocolate chips and 3 pounds of walnuts, the total cost is $14.

Find the cost for each pound of chocolate chips and each pound of walnuts.

Answer 1

w = 2.50

c = 3.25

Explanation:

Use system of equations and solve

c = chips, w = walnuts

eq1 > 4c + 8w = 33

eq2 > 2c + 3w = 14

modified eq 2 > 4c + 6w = 28

eq1-eq2 = 2w = 5

Solving:

w = 2.50

c = 3.25
