<human>:  Tara's parents gave her $90 for her birthday. Not wanting to spend it, Tara put the money in a new bank account that gains 10% interest annually. If she doesn't withdraw the money at all, how much will she have after a year?
<bot>: How much interest will Tara's account yield in one year? ** In one year, Tara's account will yield an interest of 10/100*90 = <<10/100*90=9>>9 dollars
How much money will Tara have in her account after a year? ** The total in her account will therefore be 90 + 9 = <<90+9=99>>99 dollars.
