Jaxson Corporation has the following data related to direct labor costs for September: actual costs are 10,200 hours at $15.75 per hour and standard costs are 10,800 hours at $15.50 per hour. What is the direct labor time variance?

Direct labor time (efficiency) variance= $9,300 favorable

Explanation:

Giving the following information:

actual costs are 10,200 hours at $15.75 per hour.

standard costs are 10,800 hours at $15.50 per hour.

To calculate the direct labor time (efficiency) variance, we need to use the following formula:

Direct labor time (efficiency) variance= (Standard Quantity - Actual Quantity)*standard rate

Direct labor time (efficiency) variance= (10,800 - 10,200)*15.5

Direct labor time (efficiency) variance= $9,300 favorable

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
