Final answer:
To find the cost of 6 pounds of walnuts, set up a proportion using the cost of 3 pounds. Multiply the cost of 1 pound by 6 to find the total cost.
Step-by-step explanation:
To find the cost of 6 pounds of walnuts, we can use proportional reasoning. Since 3 pounds of walnuts cost $7.14, we can set up a proportion to find the cost of 1 pound.
3 pounds / $7.14 = 1 pound / x
Cross multiplying, we get:
3 pounds * x = $7.14 * 1 pound
Simplifying, we get:
x = $21.42 / 3 pounds
So, the cost of 1 pound of walnuts is $7.14 / 3 = $2.38. To find the cost of 6 pounds, we can multiply the cost of 1 pound by 6:
6 pounds * $2.38/pound = $14.28
Therefore, 6 pounds of walnuts will cost $14.28.
