Answer 1

Answer:

429

Step-by-step explanation:

312/800 = .39

1100 x .39 = 429

Answer 2

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.
