Given:
Employee discount 15%.
Amount paid by employee - $219.30
If the discount is 15%, then the amount paid by the employee is only 85% of the original price. Therefore, to get the original price, we do this computation.
Original price = amount paid by employee ÷ (100%-employee discount)
O.P = $219.30 ÷ (100% - 15%)
O.P = $219.30 ÷ 85%
Original Price = $258
Discount : $258 * 15% = $38.70
Amount paid by employee : $258 - 38.70 = 219.30
