Step-by-step explanation:
312/800 = .39
1100 x .39 = 429
Answer:
$429
Step-by-step explanation:
--------------------
[tex]\frac{312}{800} =\frac{x}{100}[/tex]
Cross multiply
[tex]800x=31200[/tex]
Divide both sides by 800
[tex]x=39[/tex]
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.
--------------->>>>
[tex]\frac{x}{1100}=\frac{39}{100}[/tex]
Cross multiply
[tex]100x=42900[/tex]
Divide both sides by 100
[tex]x=429[/tex]
--------------------
This means that Niu $1,100 would have earned Niu $429 in the same investment.
Hope this is helpful
