Tenille made $2,000 on a summer job. She put it in a bank account paying simple interest of 5% annually. If Tenille lets her money earn interest for 10 years, how much will she have?
The annual interest that Tenille will receive is 5/100*2000 = $<<5/100*2000=100>>100
If she lets her money earn interest for 10 years, the interest after 10 years will be 100*10 = $<<100*10=1000>>1000
Let's add the interest to her initial amount to find how much she will have: $2000+$1000 = $<<2000+1000=3000>>3000. Answer: \boxed{3000}.
