Answer:
Joseph will have 1,108$ in his bank account when he opens it again.
First, we need to know how much 0.3% of 1000$ is, which is 3$.
Next, since there are 12 months in a year we multiply 3$ by 12 which is 36.
Then, since 3 years have passed we multiply 36$ by 3 which is 108$. So in conclusion, he'll have 1,108$ when he checks his account again.
