Tony puts $1,000 in a savings account for 1 year. It earns 20% interest. He then takes out half the money to buy a new TV. The next year, the remaining money earns 15% interest. How much is now in the account?
After one year he earns $200 in interest because 1,000 x .2 = <<1000*.2=200>>200
After one year it has $1,200 in the account because 1,000 + 200 = <<1000+200=1200>>1,200
He takes out $600 because 1,200 / 2 = <<1200/2=600>>600
After this it has $600 in it because 1,200 - 600 = <<1200-600=600>>600
She earns $90 in interest because 600 x .15 = <<600*.15=90>>90
The account now has $690 because 600 + 90 = <<600+90=690>>690
#### 690
