Answer:
The revenue variance is $10,249
Explanation:
Dog Kennel budgets to have 4,100 tenant-days in March, and $35 is budgeted revenue for each tenant-day. So the revenue budgeted for March is $143,500.
Because the actual revenue in March is $133,251, then revenue variance is the difference between budget and actual, $10,249 = $143,500 - $133,251
