John takes out a loan for $ 10 , 000 at a simple interest rate of 5 % to be paid back in 36 monthly installments.
andrew-mc [135]

The monthly principal and interest payment John will pay monthly is $3,750.04

<h3>What is the amount of principal and interest repayment?</h3><h3 />

Given:

  • P = 10,000
  • i = 5% / (12 months) = 0.375
  • L = 36 months

M = 10000 \times  \frac{0.375}{ {1 - (1 + 0.375)}^{ - 36} }

M = 10000 \times  \frac{0.375}{ {1 - (1.375)}^{ - 36} }

M = 10000 \times  \frac{0.375}{ {1 - (0.00001049791)} }

M = 10000 \times  \frac{0.375}{ 0.99998950208 }

M = 10000  \times  0.37500393675

M = 3750.03936758

Approximately,

M = $3,750.04

Therefore, John will be be repaying $3,750.04 monthly including principal and interest

What is the solution to the following equation?
nexus9112 [7]

Answer:

The answer to your question is the letter B. x = 6

Step-by-step explanation:

Data

               4x² - 48x = -144

Process

1.- Equal to zero

               4x² - 48x + 144 = 0

2.- Multiply 4 by 144

             4 x 144 = 576

3.- Find the prime factors of 576

                     576   2

                     288   2

                     144    2

                       72    2

                       36   2

                       18    2

                        9    3

                        3     3

                         1

4.- Find two numbers that added gives -48,

     these numbers are -24 and -24

5.- Write the equation using these numbers

              4x² -24x - 24x + 144 = 0

6.- Factor by grouping

             4x(x - 6) - 24(x - 6)

7.- Factor by like terms

             (x - 6)(4x - 24)

8.- Find the solutions

              x - 6 = 0           4x - 24 = 0                            

              x = 6                   4x = 24

                                        x = 24/4

                                        x = 6
