A variable can allow you to  guess and test.  If you had a definite answer, there would be no need to guess and test.  However, you could still use a formula to figure the answer.

A principal of 2000 is invested at 3.25% interest, compounded annually. How much will the investment be worth after 10 years?
zepelin [54]

Answer:

$2,753.79

Step-by-step explanation:

Compound Interest Formula

\large \text{$ \sf A=P\left(1+\frac{r}{n}\right)^{nt} $}

where:

  • A = final amount
  • P = principal amount
  • r = interest rate (in decimal form)
  • n = number of times interest applied per time period
  • t = number of time periods elapsed

Given:

  • P = $2,000
  • r = 3.25% = 0.0325
  • n = 1
  • t = 10

Substitute the given values into the formula and solve for A:

\implies \sf A=2000\left(1+\frac{0.0325}{1}\right)^{(1 \times 10)}

\implies \sf A=2000(1.0325)^{10}

\implies \sf A=2753.788608...

Therefore, the value of the investment after 10 years will be $2,753.79 to the nearest cent.

Which of the following are solutions to the equation below? Check all that apply.
Vesna [10]

(3x + 4)2 = 14

(3x + 4)2 means that 2 will multiply both 3x and 4

2 * 3x = 6x 2 * 4 = 8

6x + 8 = 14

Move +8 to the other side of the equation

6x = 14 - 8 Note : Moving +8 to the other side will change the sign in front of it, that is from + to -

6x = 14 - 8

6x = 6

Divide both sides by 6 because of the 6 beside the x : 6x

6x/6 = 6/6

x = 1
