Answer:

$429

Step-by-step explanation:

--------------------

\frac{312}{800} =\frac{x}{100}

Cross multiply

800x=31200

Divide both sides by 800

x=39

So, Niu earned 39% on the investment of $800

So, let's find out how much $1,100 would have earned him in the same investment.

--------------->>>>

\frac{x}{1100}=\frac{39}{100}

Cross multiply

100x=42900

Divide both sides by 100

x=429

--------------------

This means that Niu $1,100 would have earned Niu $429 in the same investment.

Hope this is helpful
