Taussig Snow Removal's cost formula for its vehicle operating cost is $1,880 per month plus $394 per snow-day. For the month of February, the company planned for activity of 13 snow-days, but the actual level of activity was 14 snow-days. The actual vehicle operating cost for the month was $7,250. The activity variance for vehicle operating cost in February would be closest to:

$394 U

Explanation:

Calculation for the activity variance for vehicle operating cost in February would be

First step is to calculate the Flexible budget

Flexible budget= $1,880 + ($394 × 14)

Flexible budget=$7,396

Second step is to calculate the Planning budget

Planning budget= $1,880 + ($394 × 13)

Planning budget=$7,002

Last step is to calculate the activity variance for vehicle operating cost in Februar

Activity variance=Flexible budget $7,396-Planning budget $7,002

Activity variance=$394 U

Therefore The activity variance for vehicle operating cost in February would be closest to $394 U.

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.'

answer; i believe the correct answer is (tall); ///good luck
