ABSTRACT:
A meeting cost calculator and timer is shown for displaying the total cost of a meeting and the elapsed time thereof. Input switches, each associated with a class of attendee, actuate an adjustable rate indicator which applies its digital signal to an arithmetic logic unit and then to an accumulator in the form of a memory register. A second set of switches add or subtract the rate applied to the accumulator depending whether the attendee is entering or leaving the meeting. A display displays the total rate of the attendees over a period of time as the total cost of the meeting.
