A $10,000 deposit at the bank will double in value in 9 years. Give a formula for the accumulated amount t years after the inves

wolverine [178]

Answer:

$S = P(1.08)^{t}$

Step-by-step explanation:

A $10,000 deposit at the bank will double in value in 9 years.

If the interest is r% and it is compounded each year, then we can write from the formula of compound interest that

$20000 = 10000(1 + \frac{r}{100})^{9}$

⇒ $2 = (1 + \frac{r}{100})^{9}$

⇒ $1 + \frac{r}{100} = 1.08$

⇒ r = 8%

Therefore, the formula for the accumulated amount t years after the investment is made will be

$S = P(1 + \frac{8}{100})^{t} = P(1.08)^{t}$

where, P is the invested principal and S is the accumulated sum. (Answer)

omeli [17]

Answer:

A. x + y = 34; 10x + 15y = 410

Step-by-step explanation:

Jody's total hours will be the sum of the hours spent on each job:

x + y = 34 . . . . . total hours

Jody's total earnings will be the sum of the earnings from each job:

10x +15y = 410 . . . total earnings

So, the system of equations is ...

x + y = 34
10x + 15y = 410
