Harper Co$.$ supplied the following data for use in its activity$-$based costing $($ABC$)$ system.

Labor$-$related overhead costs total $$250,000$

Machinery$-$related overhead costs total $$150,000.$

Below are the company$$s three cost pools and the measures related to those cost pools:

Cost pool $1$: Resource support costs are allocated based on $50,000$ total direct labor$-$hours

Cost pool $2$: Order processing costs are allocated based on $200$ orders

Cost pool $3$: General costs are facility$-$level costs

Labor$-$related overhead costs are estimated to consume $50\%$ of resource support costs, $40\%$ order processing costs, and $10\%$ of general costs. Machinery$-$related overhead costs are estimated to consume $25\%$ of resource support costs, $25\%$ of order processing costs, and $50\%$ of general costs.

What is the allocation rate used to allocate resource support costs?
