Annual fee on managed assets

Compute the fee per $10000$ units of assets first.

1. $80000000÷10000=8000$ units of $10000$.
2. Each unit of $10000$ pays $1$ per basis point, so the fee is $8000\times 45$.
3. $8000\times 45=8000\times 40+8000\times 5=320000+40000$.
4. The fee is $360000$.

Answer: $360000$
