Incorrect. First, express $\displaystyle{6.861}\cdot{{10}}^{{9}}\usepackage{cmbright}\Huge\$ in decimal notation. Be sure you've moved the decimal point the correct number of places (and in the right direction). It might help to rewrite 6.861 as 6.861000000. Multiply the result by 2 to get the predicted population of 2125.
