Vaughn Industries has three activity cost pools and two products. It estimates production $2,000$ units of Product BC$113$ and $1,000$ of Product AD$908.$ Having identified its activity cost pools and the cost drivers for each pool, Vaughn accumulated the following data relative to those activity cost pools and cost drivers.

$($a$)$ prepare a schedule showing the computations of the activity$-$based overhead rates per cost driver.

$($b$)$ Prepare a schedule assigning each activity's overhead cost to the two products.
