The answer is the first one (a): \$1,475 favorable.
To calculate the direct materials price variance, we use the formula:
\[ \text{Direct Materials Price Variance} = (\text{Actual Quantity} \times \text{Standard Price}) - (\text{Actual Quantity} \times \text{Actual Price}) \]
Given:
- Actual Quantity = 2,500 kilograms
- Standard Price = \$8.64 per kilogram
- Actual Price = \$8.05 per kilogram
Substitute the values into the formula:
\[ \text{Direct Materials Price Variance} = (2,500 \times 8.64) - (2,500 \times 8.05) \]
\[ = 21,600 - 20,125 \]
\[ = 1,475 \]
Since the actual cost is less than the standard cost, the variance is favorable.
Explanation for each option:
a. \$1,475 favorable - Correct, as calculated above.
b. \$614 favorable - Incorrect, the calculation shows a \$1,475 favorable variance.
c. \$614 unfavorable - Incorrect, both the amount and the direction of the variance are wrong.
d. \$1,475 unfavorable - Incorrect, the variance is favorable, not unfavorable.
In summary, the direct materials price variance is \$1,475 favorable.
