janice invests a total of 8000 in two different accounts. the first account returns 5%, while the second account returns 8%. if

Zinaida [17]

Answer:

"She invested $2500 in 5% account and $5500 in 8% account"

Step-by-step explanation:

Let the amount invested in 5% account be "x"

So, the amount invested in 8% account would be "8000 - x"

Interest amount is the percentage multiplied by amount invested. So

Interest of 5% account = 5% of x = 0.05x

Interest of 8% account = 8 % of 8000 - x = 0.08(8000 - x)

Total interest is the sum of these 2 expressions that EQUATES to 565 (given). Let's solve for x:

$0.05x + 0.08(8000 - x) = 565\\0.05x+640-0.08x=565\\0.03x=75\\x=2500$

and thus,

"8000 - x" = 8000 - 2500 = 5500

Hence,

She invested $2500 in 5% account and $5500 in 8% account

Answer:

About $1,178,974

Step-by-step explanation:

Alright, the sequence we have right now is:

500,000 550,000 605,000

We want to find the common ratio, so let's divide 550,000 by 500,000 and see if we get the same value as 605,000 divided by 550,000:

550,000/500,000 = 1.1

605,000/550,000 = 1.1

Now, we know that r = 1.1. We also know the first term is: $a_1$ = 500,000.

We use the explicit rule of a geometric sequence:

$a_n=a_1*r^{n-1}$

Here, we want to find $a_{10}$ , which means that n = 10. We know r and $a_1$ , so we just plug in these values:

$a_{10}=500,000*(1.1)^{10-1}=500,000*(1.1)^{9}$ ≈ $1,178,973.85$ ≈ $1,178,974$

Thus, the answer is about $1,178,974.

Hope this helps!
