Answer:
834 years.
Step-by-step explanation:
Let [tex]y[/tex] equal years.
Construct an equation:
[tex]1200y=1000000[/tex]
Divide both sides of the equation by the coefficient of [tex]y,[/tex] which is [tex]1200[/tex]:
[tex]y=833.3333...\\[/tex]
Round up to the nearest whole number:
[tex]y=834[/tex]
