Shelby Boat Wash's cost formula for its cleaning equipment and supplies is $2,940 per month plus $35 per boat. For the month of September, the company planned for activity of 73 boats, but the actual level of activity was 29 boats. The actual cleaning equipment and supplies for the month was $4,010. The activity variance for cleaning equipment and supplies in September would be closest to:

$1,540

Explanation:

Calculation for the activity variance for cleaning equipment and supplies in September

First step is to calculate for theFlexible budget

Using this formula

Flexible budget =[Cleaning equipment and supplies +(Amount per boat ×Actual level of activity)

Let plug in the formula

Flexible budget =[$2,940 + ($35 × 29)]

Flexible budget =$2,940+$1,105

Flexible budget =$3,955

Second step is to calculate for the Planning budget using this is formula

Planning budget =[Cleaning equipment and supplies +(Amount per boat ×Planned activity ]

Let plug in the formula

Planning budget= [$2,940 + ($35 × 73)]

Planning budget=$2,940+$2,555

Planning budget=$5,495

Now let calculate for the activity variance

Using this formula

Activity variance=Flexible budget-Planning budget

Let plug in the formula

Activity variance=$3,955-$5,495

Activity variance=$1,540 Favorable

Therefore the Activity variance for cleaning equipment and supplies in September is closest to:$1,540 Favourable reason been that the flexible budget is lesser than the planning budget
