Walsh Corporation has an activity$-$based costing system with three activity cost pools$-$Machining, Order Filling, and Other. In the first stage allocations, costs in the two overhead accounts, equipment depreciation and supervisory expense, are allocated to the three activity cost pools based on resource consumption. Data used in the first stage allocations follow:

Overhead costs:$$Equipment depreciation$$51,000$Supervisory expense$$3,000$

Distribution of Resource Consumption Across Activity Cost Pools:

$$Activity Cost Pools$$MachiningOrder FillingOtherEquipment depreciation$0\mathrm{.}400\mathrm{.}100\mathrm{.}50$Supervisory expense$0\mathrm{.}200\mathrm{.}300\mathrm{.}50$

Machining costs are assigned to products using machine$-$hours $($MHs$)$ and Order Filling costs are assigned to products using the number of orders. The costs in the Other activity cost pool are not assigned to products. Activity data for the company's two products follow:

Activity:

$$MHs $($Machining$)$Orders $($Order Filling$)$Product J$39,100100$Product F$7900900$Total$10,0001,000$

Finally, the costs of Machining and Order Filling are combined with the following sales and direct cost data to determine product margins.

Sales and Direct Cost Data:

$$Product J$3$Product F$7$Sales $($total$)$$$145,200$$$90,700$Direct materials $($total$)$$$81,400$$$38,600$Direct labor $($total$)$$$37,700$$$42,400$

The activity rate for the Order Filling activity cost pool under activity$-$based costing is closest to:
