a computer salesperson said she would drop the price of a computer by $120, which was a 15% discount. what was the original selling price of the computer?
It was dropped by $120 which was a 15% discount.
Let the original price be x.
15% of x = $120
(15/100)x = 120
0.15x = 120
x = 120 / 0.15
x = 800
Hence the original price was $800.
