Mathematics
1 answer:
Ronch [10]3 years ago
8 0
Solution:

x/3-2/5 = 2x/15-3/5

(x/3)/15 - (2/5)/15 = (2x/15)/15 - (3/5)/15
5x - 6 = 2x - 9
5x = 2x - 9 + 6
5x - 2x = -9 + 6
3x = -3
3x/3 = -3/3
x = -1

Therefore the value of x is -1

How much must you deposit in an account that pays 6.25% interest, compounded annually, to have a balance of $700 after two years
Amanda [17]

The compound interest is applied to the remaining balance in the account

each subsequent year.

  • The amount that must be deposited is approximately <u>$620.07</u>

Reasons:

The given compound interest rate, r = 6.25% = 0.0625

The balance in the account after 2 years, A = $700

Required:

The required deposit, <em>P</em>, that gives the given account balance after 2 years.

Solution:

The following is the compound interest formula to use;

  • A = \mathbf{P \times \left(1+r \right)^{ t}}

Where;

t = 2 years

We get;

\displaystyle P = \mathbf{ \frac{A}{(1 + r)^t}}

Which gives;

\displaystyle P = \frac{700}{(1 + 0.0625)^2} \approx  \mathbf{620.07}

  • The amount that must be deposited to give $700 after 2 years is P ≈ <u>$620.07</u>
