Linda won $200,000 in a state lottery. She first paid income tax on 30% on the winnings. She invested some of the rest at 1.5% a
Lady_Fox [76]

She invested $ 50000 at 1.5% rate and $ 90000 at 4% rate.

<u><em>Explanation</em></u>

Total amount of winnings = $ 200000

She first paid income tax on 30% on the winnings. So, the amount paid as income tax =(200000*0.30)dollar=60000 dollar.

<u>Remaining amount</u> = $ 200000 - $ 60000 = $ 140000

Suppose, she invested  x dollar at 1.5% rate.

That means, she invested (140000-x) dollar at 4% rate.

Given that, the total amount of interest earned = $ 4350

So, the equation will be.....

0.015x+0.04(140000-x)=4350\\ \\ 0.015x+5600-0.04x=4350\\ \\ -0.025x= 4350-5600\\ \\ -0.025x=-1250\\ \\ x= \frac{-1250}{-0.025}=50000

So, amount of investment at 1.5% rate = $ 50000

and amount of investment at 4% rate = $ 140000 - $ 50000 = $ 90000

PLEASE HELP (WILL NAME BRAINLYEST)
ira [324]

Answer:

4.04 x 10^0 people/km^2 (x 10^0 is fairly redundant but if the answer is required in standard form then include it)

Step-by-step explanation:

Population Density = Population/Area

= 3.11 x 10^7 / 7.69 x 10^6

= 31,100,000 / 7,690,000

= 3110 / 769

= 4.04

= 4.04 x 10^0

20 is what percent of 50? A. 40% B. 10% C. 250% D. 30%
zvonat [6]
<span>A is the correct answer. To find 10% of 50, divide it by 10. This gives you 5. If 5 is 10%, then 20 is 40%, because 20 is 4 x 5 and 40 is 4 x 10. </span>
