Use electricity cost $$0\mathrm{.}08$ to $$0\mathrm{.}30$ in increments of $$0\mathrm{.}01$ in a column. Compute a column for each type and wattage bulb, a totals column for each type of bulb, and a savings column $(10$ columns$).$ In the formulas, refer to cells containing the various input parameters instead of using the numbers. There should be no numeric values in any formulas, except for time conversions $(24$ hrs$/$day$,365$ days$/$yr$,$ etc$)!!$ Use appropriate formatting for all labels and numbers.
