Final answer:
To find the difference between the standard and actual price per pound of materials, we use the materials price variance which is calculated as (Standard Price - Actual Price) x Actual Quantity. With a favorable variance of $4,000 for 20,000 pounds of materials, the difference between the standard and actual price is $0.20 per pound.
Step-by-step explanation:
The question asks for the difference between the standard and actual price paid for materials given a materials price variance that is $4,000 favorable. To calculate this, we need to know that materials price variance is calculated as (Standard Price - Actual Price) x Actual Quantity. A favorable variance means that the actual price is less than the standard price.
Given that the variance is $4,000 favorable, we can set up the equation as follows:
(Standard Price - Actual Price) x 20,000 pounds = $4,000
Standard Price - Actual Price = $4,000 / 20,000 pounds
Standard Price - Actual Price = $0.20 per pound
The difference between the standard price and the actual price is $0.20 per pound.
