Experience has taught Brenda that as the registration fee for the seminar increases, the number of attendees willing to pay decreases. Based data from other seminars, Brends has defined a relationship between attendance and registration fee, shown in the range R4:X21 on Budget worksheet. In cell B5 of the Budget worksheet, change the number of attendees for a given registration fee based on the valus in cell B6. (Hint: Look at the formulas in the range S6:S21 to learn how to translate this equation into Excel formula.)
