The process for renewing a driver's license at the Archer County Courthouse is as follows. First, the clerk fills out the application; then the clerk takes the driver's picture; and finally a typist enters the info into the computer system and processes the new license. It takes an average of six minutes to fill out an application, one minute to take a picture, and eight minutes to process the new license. If $40$ drivers are to be processed each hour, how many clerks and typists should be hired assuming an $84$ percent target utilization rate? Do not round intermediate calculations. Round your answers up to the nearest whole number. $\_\_\_\_\_\_$clerks and $\_\_\_\_\_$ typists should be hired.
