Answer:
$10 = price of flash drive
A store manager marked up a $10 flash drive by 20%.
10 * 1.2 = $12
She then marked it down by 20%.
12 * 0.8 = $9.60
Explain why the new price of the flash drive is not $10.
20% of the original price, $10, is less that 20% of the marked up price, $12. This means the store manager lost more than she gained. Hence the price is not $10.
