Lucy invested $10,000 in a new mutual fund account exactly three years ago. The value of the account increased by 10 percent during the first year, increased by 5 percent during the second year, and decreased by 10 percent during the third year. What is the value of the account today?
(A) $10,350
(B) $10,395
(C) $10,500
(D) $11,500
(E) $12,705
Start: $10,000
First year +10% 10% of $10,000 = $1000
So, we get $10,000 + $1000 =
$11,000 Second year +5% 5% of
$11,000 = $550
So, we get
$11,000 + $550 =
$11,550 Third year -10% 10% of
$11,550 = $1,155
So, we get
$11,550 - $1155 = $10,395
Answer: B
