MaRussiya [10]

Answer:

The payment is k=\$3216.92.

Interest paid during the 3-year period is I_{T}=\$1651.76

Step-by-step explanation:

Hi

<u>The Payment amount</u>

We are going to use the formula below with VP=\$8000, i=10\% and n=3.

k=\frac{VP}{[\frac{1-(1+i)^{-n}}{i}] } =\frac{8000}{[\frac{1-(1+0.1)^{-3}}{0.1}] }=3216.92

<u>Interest paid during the 3 year</u>

  • <u>First period</u>

I_{1}=VP*i=8000*0.1=800

CS_{1}=k-I_{1}=3216.92-800=2416.92

Balance_{1}=VP-CS_{1}=8000-2416.92=5583.08

  • <u>Second period</u>

I_{2}=B_{1}*i=5583.08*0.1=558.31

CS_{2}=k-I_{2}=3216.92-558.31=2648.61

Balance_{2}=VP-CS_{2}=5583.08-2648.61=2924.47

  • <u>Third period</u>

I_{3}=B_{2}*i=2924.47*0.1=292.45

  • Sum of Interest paid during the 3 years

I_{t}=I_{1}+I_{2}+I_{3}=800+558.31+292.45=1651.76

Solve the following system of equations by substitution and select the correct answer below:
Cerrena [4.2K]

Answer:

A

Step-by-step explanation:

Start with variable x.
4x - 6y = 28
Substitute the variables for numbers.
4(1) - 6(-4) = 28
Solve the new equation
4 + -24 = 28

Move to the second equation with variable y.
8x - 4y = 24
Substitute variables
8(1) - 4(-4) = 24
Solve
8 - (-16) = 24

The answer is A, x = 1, y = -4

. Find the area of a trapezoid with b1 = 13.8 cm, b2 = 16.8 cm, and h = 4 cm.
Ilia_Sergeevich [38]

Answer:

61.2 cm²

Step-by-step explanation:

The area (A) of a trapezoid is calculated using the formula

A = \frac{1}{2} h (b_{1} + b_{2} )

Substitute in given values

A = \frac{1}{2} × 4 × (13.8 + 16.8 ) = 2 × 30.6 = 61.2 cm²
