Question

Niu earned $312 on an investment of $800. How much would $1100 have earned in the same

investment?

Answer 1

429

Explanation:

312/800 = .39

1100 x .39 = 429

Answer 2

$429

Explanation:

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

`(312)/(800) =(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.

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

`(x)/(1100)=(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
