Answer:
The activity variance for cleaning equipment and supplies in April would be closest to = -$225
Step-by-step explanation:
Cost formula for cleaning equipment and supplies = $2,540 + $45 per boat
Since the actual level of activity is 11 boats the budgeted costs for 11 boats will be $2,540 + $45*11 = $3,035
Actual costs for the 11 boats = $3,260
Activity variance = Budgeted - Actual activity cost = $3,035 - $3,260
= -$225
Since the actual cost of activity is more than budgeted cost of activity, the activity variance is unfavorable and closest to -$225.
