Question 9 of 10 Which of these groups of values plugged into the TVM Solver of a graphing calculator will return the same value
hodyreva [135]

The TVM solver is a tool found in graphing calculators, that solve Time Value of Money problems.

The group of values that will return the same value as the given expression is;

D. N = 24; I% = 3.6; PV =; PMT = -415; FV = 0; P/Y = 12; C/Y = 12; PMT :END

<h3>What is Present Value?</h3>

Present value (PV) formula finds application in finance to calculate the present day value of an amount that is received at a future date.

In the TVM solver, we have;

I = The annual percentage rate

N = n × t

t = The number of years

PV = Present value

PMT = Payment

P/Y = Number of payments per year = n

C/Y = Number of compounding periods per year = n

The formula for monthly payment is presented as follows;

P = \frac{M[(1+r/n)^{nt} - 1]}{(r/n)(1+r/n)^{nt}}

M = \frac{P.(r/n)(1+ r/n)^{nt} }{(1+ r/n)^{nt} - 1}

Therefore, we get;

Where;

M = PMT = -415

P = PV

r = I

P/Y = n = 12

Therefore;

0.003 = I/12

I = 0.003 X 12 = 3.6%

N = n X t = 24

The value of the equation is the present value, PV = ?

When payment are made based on the PV, we have FV = 0

The group of values the same value as the expression

P = \frac{(415)[(1+0.003)^{24}-1]}{(0.003)(1+0.003)^{24}}

when plugged into the TVM solver of a calculator is;

D. N = 24; I% = 3.6; PV =; PMT = -415; FV = 0; P/Y = 12; C/Y = 12; PMT :END

Please help me
elena55 [62]

Answer:

a)

<u>The equation would be:</u>

  • 3x + 2 = 7*2

b)

Step 1. <u>Subtract 2 from both sides:</u>

  • 3x = 6*2

Step 2. <u>Divide both sides by 3:</u>

  • 3x/3 = 6*2/3
  • x = 2*2

c)

  • A single box weights x= 4 units.

Akimi4 [234]

Answer: T=1/2 Y + -5/2

Step-by-step explanation:

y=2t+5

2t+5 +-5= y +-5

2t=y-5 2t/2=y-5/2

t=1/2y+-5/2

= t=1/2y + -5/2
