Bob invested $11,000, part at 20% and part at 13%. If the total interest at the end of the year is $1,990.?

Is this for school? If I had a caculator I could prob figure it out but my bro still has mine, I'm sorry.

$8,000 at 20% and $3,000 at 13%

8,000 x .20 = 1600
3,000 x .13 = 390

1600 + 390 = 1990
