The standard amount of materials required to make one unit of Product Q is 4 pounds. Tusa's static budget showed a planned production of 4,000 units. During the period the company actually produced 4,100 units of product. The actual amount of materials used averaged 4.1 pounds per unit. The standard price of material is $1 per pound. Based on this information, the materials usage variance was:

(4.1 x 4,100 – 4 x 4,100) x $1=$410 unfavorable

To find the materials usage variance, we need to calculate the difference between the actual amount of materials used and the standard amount of materials required, multiplied by the standard price of materials.

First, let's calculate the standard amount of materials required for the planned production of 4,000 units:
Standard amount of materials required = 4 pounds per unit * 4,000 units = 16,000 pounds

Next, we calculate the standard amount of materials required for the actual production of 4,100 units:
Standard amount of materials required = 4 pounds per unit * 4,100 units = 16,400 pounds

Now, let's calculate the materials usage variance:
Materials usage variance = (Actual amount of materials used - Standard amount of materials required) * Standard price of materials

Actual amount of materials used = 4.1 pounds per unit * 4,100 units = 16,740 pounds

Materials usage variance = (16,740 pounds - 16,400 pounds) * $1/pound
Materials usage variance = 340 pounds * $1/pound = $340

Therefore, the materials usage variance is $340.

To calculate the materials usage variance, we need to find the difference between the actual materials used and the standard materials required, and then multiply it by the standard price of materials.

Step 1: Calculate the standard materials required:
Standard materials required per unit = 4 pounds
Standard materials required for 4,100 units = 4 pounds/unit * 4,100 units = 16,400 pounds

Step 2: Calculate the actual materials used:
Actual materials used per unit = 4.1 pounds
Actual materials used for 4,100 units = 4.1 pounds/unit * 4,100 units = 16,810 pounds

Step 3: Calculate the materials usage variance:
Materials usage variance = (Actual materials used - Standard materials required) * Standard price
Materials usage variance = (16,810 pounds - 16,400 pounds) * $1/pound
Materials usage variance = 410 pounds * $1/pound
Materials usage variance = $410

Therefore, the materials usage variance is $410.
