Correct. The 2010 population was $\displaystyle{6.861}\cdot{{10}}^{{9}}={6},{861},{000},{000}\usepackage{cmbright}\Huge\$ (since multiplying by $\displaystyle{{10}}^{{9}}\usepackage{cmbright}\Huge\$ has the same effect as moving the decimal point 9 places to the right), so the 2125 population was predicted to be $\displaystyle{2}\cdot{6},{861},{000},{000}\usepackage{cmbright}\Huge\$ , which equals 13,722,000,000.
