Question

an item initially valued at 100$ goes down in value by 20% the first year then goes up in value 10% the second year and goes down again by 20% in the third year. what is the value of the item at the end of the third year

Answer 1

$100 * 0.2 = $20.
$100 - $20 = $80.
$80 * 0.1 = $8.
$80 + $8 = $88.
$88 * 0.2 = $17.60
$88 - $17.60 = $70.40.
Answer: $70.40
