suter [353]

Answer:Amount = 10,002.21



Step-by-step explanation:4 x 5 = 20 times


2.-

Principal = 5,000

Interest rate per yr = 3%

Compounded times per yr = 4

Time in years = 5


The formula is amt = p*(1 + r/n) ^ (n*t),

thus

Amount = 5,805.92


3.-

If Time in years = 23.2

then

Amount = 10,002.56


4.-

Principal = 5,000.00

Interest rate per yr = 5.82%

Compounded times per yr = 4

Time in years = 12

Can someone please help me?
Lena [83]

Hey there!

We can solve systems two ways - substitution and elimination. It seems in this case that elimination is going to be easier.


Let's begin by multiplying the top equation by 3, and the bottom equation by 4:

3(5x - 4y = -24)

15x - 12y = -72


4(4x + 3y = 18)

16x + 12y = 72


Next, we'll add the two equations together to get rid of, or eliminate, the y variable and solve for the x variable:

(15x - 12y = -72) + (16x + 12y = 72)

31x = 0

x = 0


Next, we'll plug the value of the x variable into the top equation and solve for the y variable:

5(0) - 4y = -24

-4y = -24

y = 6


Therefore, x = 0 and y = 6.


Hope this helps!! :)
